• What is the cause and solution for SAP error message FMBAPI002 - Distribution key and period amounts filled simultaneously ?

  The SAP error message FMBAPI002 indicates that there is an issue with the distribution key and period amounts being filled simultaneously in a financial transaction or posting. This error typically arises in the context of budget management or financial planning within SAP, particularly when using the Funds Management (FM) module.
  Cause:
  The error occurs when both the distribution key and the period amounts are specified at the same time in a transaction. In SAP, the distribution key is used to allocate amounts across different periods or cost centers, while period amounts are used to specify the exact amounts for each period. The system does not allow both to be filled simultaneously because it creates ambiguity in how the amounts should be allocated.
  Solution:
  To resolve the FMBAPI002 error, you should ensure that only one of the two fields (distribution key or period amounts) is filled in the transaction. Here are the steps to follow:
  
  
  Review the Transaction: Go back to the transaction where the error occurred and check the fields for the distribution key and period amounts.
  
  
  Decide on Allocation Method:
  
  If you want to use a distribution key, ensure that the period amounts are left blank.
  If you want to specify amounts for each period, then clear the distribution key field.
  
  
  
  Re-enter the Data: After making the necessary adjustments, re-enter the data and try to execute the transaction again.
  
  
  Test the Changes: After making the changes, test the transaction to ensure that it processes without errors.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for Funds Management for more detailed information on how to use distribution keys and period amounts.
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP FM, such as FMBB (Budgeting) or FMAVCR01 (Budget Availability Control).
  User Exits and BAdIs: If you are customizing the behavior of budget postings, check if there are any user exits or Business Add-Ins (BAdIs) that might be affecting the behavior of the distribution key and period amounts.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in the Funds Management module for further assistance.
