How To Fix FDM_MIRROR144 - BAdI implementation is not compatible with the previous implementation

SAP Error Message - Details

• Message type: E = Error

• Message class: FDM_MIRROR - Mirror System Messages

• Message number: 144

• Message text: BAdI implementation is not compatible with the previous implementation

What causes this issue?

The Business Add-In (BAdI) for this implementation can be used more than
once, meaning there can be several active implementations.
The program has already executed an implementation that has only loaded
changes. Loading of changes is <ZH>not</> supported, however, by the
implementation that you now want to execute. This is the reason why the
two implementations are not compatible.

System Response

Loading the data is terminated.

How to fix this error?

Carry out the two implementations in such a way that they are
compatible.
Start the program again for loading the data.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message FDM_MIRROR144 - BAdI implementation is not compatible with the previous implementation ?

  The SAP error message FDM_MIRROR144 indicates that there is an issue with the implementation of a Business Add-In (BAdI) related to the Financial Data Management (FDM) component. Specifically, it suggests that the current implementation of the BAdI is not compatible with a previous implementation. This can occur due to various reasons, such as changes in the BAdI interface, modifications in the underlying data model, or inconsistencies in the implementation logic.
  Causes:
  
  Interface Changes: The BAdI interface may have been modified in a way that is not compatible with the previous implementation.
  Multiple Implementations: There may be multiple implementations of the BAdI, and the system is unable to determine which one to use due to conflicts.
  Versioning Issues: If the system has been upgraded or patched, the new version may have introduced changes that are not compatible with the existing implementations.
  Incorrect Configuration: The configuration settings for the BAdI may not be set correctly, leading to compatibility issues.
  
  Solutions:
  
  Check BAdI Implementation: Review the current implementation of the BAdI to ensure it adheres to the expected interface and logic. You may need to adjust the implementation to align with the new requirements.
  Remove Conflicting Implementations: If there are multiple implementations of the BAdI, consider deactivating or removing the ones that are not needed or that conflict with the current implementation.
  Re-implement the BAdI: If the implementation is outdated or incompatible, you may need to create a new implementation of the BAdI that is compatible with the current system version.
  Consult Documentation: Review the SAP documentation for the specific BAdI to understand any changes that may have been introduced in recent updates or patches.
  Check for Notes: Look for SAP Notes related to the BAdI in question. SAP may have provided guidance or fixes for known issues.
  Testing: After making changes, thoroughly test the implementation to ensure that it works as expected and does not introduce new issues.
  
  Related Information:
  
  BAdI Definition: Business Add-Ins (BAdIs) are a type of enhancement technique in SAP that allows developers to add custom functionality to standard SAP applications without modifying the original code.
  Transaction Codes: You can use transaction codes like SE18 (to display BAdI definitions) and SE19 (to implement BAdIs) to manage BAdI implementations.
  SAP Support: If the issue persists after attempting the above solutions, consider reaching out to SAP Support for further assistance.
  
  By following these steps, you should be able to resolve the FDM_MIRROR144 error and ensure that your BAdI implementation is compatible with the current system configuration.
