• What is the cause and solution for SAP error message FKK_ID_JP045 - When existing value is inserted in &1, do not enter value in &2 ?

  The SAP error message FKK_ID_JP045 typically occurs in the context of the SAP Convergent Charging or SAP Contract Accounts Receivable and Payable (FI-CA) modules. This error message indicates that there is a conflict in the data entry where a value is being inserted into a field that already has an existing value, and the system is enforcing a rule that prevents this.
  Cause:
  The error message "When existing value is inserted in &1, do not enter value in &2" suggests that:
  
  You are trying to enter a value in field &2 while there is already a value present in field &1.
  The system has a validation rule that requires either field &1 or field &2 to be filled, but not both at the same time.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Field Values: Review the values in both fields (&1 and &2). Determine which field currently has a value and which one you are trying to populate.
  
  
  Clear the Conflicting Field: If field &1 already has a value, you should either:
  
  Remove the value from field &1 if it is not needed.
  Leave field &2 empty if you intend to keep the value in field &1.
  
  
  
  Consult Documentation: If you are unsure about the purpose of these fields, refer to the relevant SAP documentation or consult with your SAP functional consultant to understand the business logic behind these fields.
  
  
  Adjust Configuration: If this behavior is not desired, and you believe that both fields should be allowed to have values simultaneously, you may need to review the configuration settings in the system. This may involve adjusting validation rules or field dependencies.
  
  
  Testing: After making the necessary changes, test the transaction again to ensure that the error no longer occurs.
