Simple Rules to changing Document in SAP S/4HANA

SAP Document Changing Rules

Rules in the context of making changes to SAP documents serve as guidelines for both permissible and restricted changing actions. The changing rules outline which elements can be modified and which cannot. Some fields, like company code, business area, account number, posting key, amount, and currency, are typically unchallengeable once a document is posted. However, specific fields within the SAP S/4HANA document line items, such as payment method, payment block, house bank, dunning level, and dunning block, can be modified, subject to specific rules and procedures.


The SAP document changing rules apply regardless of whether changes are made in a single step or several steps. Also, the changes are accurately tracked and recorded by user identity to establish a comprehensive audit trail.

What is SAP Document Change?

The term “SAP Document Changes” typically implies the process of modifying or updating data within posted documents or records in the SAP software ecosystem. The SAP document changes will adhere to defined rules and controls, ensuring that the SAP system remains accurate, compliant, and aligned with the organization’s business needs.


The SAP documents subjected to modification can encompass a wide range of business transactions and processes, including financial transactions, sales orders, purchase orders, invoices, material master records, customer and vendor records, and more.


The changes in SAP documents could involve correcting errors, updating information, adjusting quantities or amounts, changing dates, and other relevant modifications.

What are the SAP Document Change Rules?

SAP Document Change Rule refers to a set of predefined or customized guidelines and controls. These rules determine how changes to certain types of documents or records are managed within the system. These rules are usually configured to enforce specific behaviors and restrictions when modifying documents to ensure data accuracy, integrity, and compliance with organizational policies and regulations. SAP document change rules define changeable fields, authorized personnel, and conditions for changes. An audit trial is upheld to ensure transparency and accountability when changes are made to the SAP document.

SAP Document Change Rules can be made by following the criteria

To maintain accounting data accuracy, SAP governs editable fields. However, after posting, the listed specific fields can be modified using standard procedures.


  1. Document number
  2. Company code
  3. Fiscal year

Rules Governing SAP Document Change

Following are a few of the SAP document change rules:

  • Modifications are permitted for New General Ledger (G/L) fields. However, it’s important to note that document changes affect the BSEG table and may result in data inconsistency between the entry view and the New G/L view.
  • Special ledger fields should not be altered as that could result in data inconsistency between the financial tables and the special ledger.

Conditions for Executing SAP Document Changes

  • Changes can be enabled when the document adheres to specific conditions as listed below:
  • The posting period should be currently open.
  • The line item within the document hasn’t been cleared (for accounts that track open items).
  • The line items should be either a debit entry to a Customer’s account or a credit entry to a Vendor’s account.
  • The document should not be a credit memo linked to an invoice.
  • The document should not be a credit memo originating from a down payment.

When can the SAP Document Change Rule be Used?

When there’s a necessity to modify the non-editable data in an SAP document, without the requirement to reverse the entire document, SAP Document Change Rules can be applied.

SAP Document Change Rules enable changing non-editable data when there is a need to:

  • Rectify errors in non-editable data fields while maintaining an audit trail
  • Change vendor information when there are valid reasons to do
  • Update customer returns or adjustments, such as changing the quantity of returned goods
  • Make changes that are mandated by regulatory requirements.
  • Modify data as required by regulations or audits for compliance reasons.
  • Modify historical data for reporting or auditing purposes.

How to Perform Field Change Rules in SAP Documents?

Field change rules in SAP documents serve to create exact and regulated guidelines for changing important data within the SAP system. The following outlines the steps to execute a rule for field changes in SAP documents:

Step 1: Choose the Field

Initially, you have to pick the specific field you want to allow changes to. To pick the specific fields:


Enter the T-code- FB02 to view the document related to that company code and Fiscal year


Among the listed items on the screen, you have to choose the item in which you want to change the field. ​


For example, if you intend to make changes to the “Terms of Payment” field, you have to select that.


Technically, the “Terms of Payment” field will be identified as “BSEG-ZTERM.”

Step 2: Define Where the Rule Applies

Next, you should decide where the rule should apply:

  • You can choose to apply it to specific types of accounts, like Assets, Vendors, Customers, Materials, or General Ledger (G/L) accounts. Or, if you want it to apply to all account types, you can leave the checkbox part blank.
  • If the rule is intended for special transactions, like unique financial situations, you can specify that in the “Transact. Type” box. If not, you can leave the checkbox blank.
  • If the rule should only work for a particular company within your organization, you have to enter that company code in the given box. If it should apply to all company codes, you can leave the company code part blank.

Step 3: Allow or Prevent Changes

You have to decide whether the field can be changed or not. If you want the field to be changeable, you should check the “Fields Can Be Changed” checkbox.  


Step 4: Add Specific Conditions

Finally, you need to set some specific conditions for when the field can be changed:

If you want the field to be changeable only when the posting period (a specific time frame) is still open, you have to check the “Posting period not closed” checkbox.

  • If you want changes to be allowed only when the line item (the specific transaction) hasn’t been settled or cleared yet, you have to check the “Line item not cleared” checkbox.
  • If the field should be modifiable only for certain transactions, like when money is owed by a Customer or owed to a Vendor, you have to check the “Customer Debit or Vendor Credit” checkbox.
  • If the field shouldn’t be changed for credit memos (documents that reduce what’s owed), you need to check the “No invoice-related credit memo” checkbox.
  • Lastly, if it shouldn’t be changed for credit memos created from the transfer of down payments, you need to check the “No credit memo from down payment” checkbox.

By following these steps, you’re creating a rule that specifies when and where changes can be made to a particular field in your SAP documents, ensuring data accuracy and consistency.


Once you input the required conditions, the specified details will activate the selected field as an editable field.


Document changing rules play a crucial role in safeguarding data integrity, complying with regulatory requirements, and facilitating smooth audit trails. In the dynamic landscape of SAP S/4HANA, mastering document changing rules is an indispensable component of efficient and compliant business processes. By adhering to defined conditions, organizations can ensure that document changes occur under controlled circumstances. Moreover, the ability to customize rules based on account types, company codes, and other criteria will empower businesses to align document changes with their unique operational needs. 


Implementing SAP S/4HANA document changing rules is significant for data accuracy and compliance. The document changing rules governed by SAP allows flexibility while maintaining controls. Changes should align with business processes, controls, and auditability to prevent unauthorized modifications, ensuring compliance and security standards.  


Changing document configuration in SAP involves modifying settings and rules related to document management. Within the scope of changing rules in SAP, particularly for document fields, follow these steps: 

  • Field Selection: Start by selecting the specific field you want to define a rule for using its field name. 
  • Area of Validity: Specify the account type to which the rule should apply. For instance, rules can differ between Customer and Vendor transactions. However, document header fields usually apply universally, so no account type is specified for them. 
  • Transaction Class (if needed): If your rule is meant for special G/L transactions like bills of exchange or down payments, you can specify a transaction class. This ensures the rule applies exclusively to these specialized transactions. 
  • Company Code (if applicable): To make rules specific to certain company codes, enter the relevant company code for the field. Otherwise, the rule without a company code applies universally. 
  • Field Changeability: Decide if the field should be changeable or not. If it should be, check the “Field Is Changeable” checkbox; otherwise, leave it unchecked. 
  • Prerequisites for Change: Set conditions for when the field can be changed based on predefined factors. In your case, these factors include an open posting period, an uncleared line item, specific debit or credit postings to customer or vendor accounts, and the absence of credit memos referring to invoices or from down payments. 

By following these steps, you can effectively define and modify rules for SAP document fields, ensuring accurate data management within your SAP system. 

During the processing of sales documents, it is possible to change the document type to perform actions such as converting an inquiry into a quotation or transforming a saved inquiry into a standard order. 


 In the overview screen (Sales tab page) during document processing, changing the sales document type is a simple process.  

  • Users can select the desired document type from the available options. 
  • Users can configure which sales document types can be offered as alternatives during document processing using the settings.  
  • Customizing for sales document types allows for the definition of two alternative document types for each primary sales document type. These alternatives are specified using the “Alt.sales doc. type1” and “Alt.sales doc. type2” fields. 

While the steps to change a document are simple, it’s significant that the document complies with the specified criteria. Thus, by adhering to the following defined settings and checks, you can efficiently manage and convert sales documents.  

 System Checks: 

  • The system performs specific checks on the defined alternative sales document types to ensure they meet certain criteria. 
  • The selected sales document type must not be blocked (Sales document block field). 
  • There should not be an indicator set for the sales document type (Indicator field). 
  • The settings in the Item division fields must match both the original and alternative document types. This consistency ensures that the division specified in the sales document header applies to all items. 

System Settings: 

Various procedures and settings must align between the original and alternative document types, including: 

  •  Payment guarantee procedure 
  • Partner determination procedure 
  •  Text determination procedure 
  •  Status procedure 
  •  Hierarchy category for pricing 
  • Billing plan type/invoice plan 
  • Payment card planning type  
  • Promotion/receiving point determination (applies to Retail settings) 
  • Commitment data 
  • Checking group for payment cards

A document type is a fundamental classification key in accounting, helping differentiate and categorize business transactions. It’s recorded in the document header and applies to the entire document. Here are the key document types in the standard system:  

  • AB – General document 
  • CO – CO posting 
  • DG – Customer credit memo 
  • DZ – Customer payment 
  • DR – Customer invoice 
  • KZ – Vendor payment 
  • KG – Vendor credit memo 
  • KN – Vendor net invoice and credit memo 
  • KR – Vendor invoice 
  • SA – General G/L accounts 

Document types serve several essential purposes: 

Transaction Identification: They distinguish various business transactions. Every line item carries the document type, making it easy to identify the nature of each transaction, aiding evaluation. 

Control Account Types: Document types determine which account types (Vendor, Customer, or General Ledger) a specific document can be posted to, ensuring accurate accounting. 

Document Number Assignment: Each document type in SAP is linked to a specific number range. This ensures that original documents are sequentially stored together for orderly recordkeeping.

Holding and Parking Document types in SAP FICO serve the purpose of temporarily pausing or submitting documents for higher authority approval. While they share a common objective, there are similarities and differences between the two: 


Non-Impact on Transaction Figures: Neither parking nor holding documents update transaction figures, ensuring they don’t affect financial data. 

Account Evaluation: Parking documents, though not affecting transaction figures, can be considered for account evaluation and tax purposes. 


Number Assignment: Holding documents are assigned temporary numbers, whereas parking documents retain their original numbers. 

Visibility: Both can be deleted and posted, but holding documents cannot be viewed in Account Display, whereas parking documents can be viewed in Account Display 

User Assignment: Parking documents have internally assigned document numbers and can be viewed/modified by any user. In contrast, holding documents have user-assigned document numbers and cannot be accessed or changed by other users. 

Hold and park documents serve as temporary document management tools in SAP, each with its distinct characteristics while sharing the common feature of not impacting transaction figures.
