• What is the cause and solution for SAP error message APO_BAPI385 - Application log &1 is not open yet ?

  The SAP error message "APO_BAPI385 Application log &1 is not open yet" typically occurs in the context of Advanced Planning and Optimization (APO) when there is an attempt to access an application log that has not been opened or initialized. This can happen during the execution of BAPIs (Business Application Programming Interfaces) or other processes that rely on application logs for tracking and debugging.
  Cause:
  
  Log Not Initialized: The application log has not been opened for the current session or transaction. This can happen if the process that is supposed to create the log has not been executed yet.
  Incorrect Log Identifier: The log identifier being referenced may be incorrect or does not correspond to an existing log.
  Timing Issues: There may be timing issues where the log is expected to be opened but is not yet available due to the sequence of operations.
  
  Solution:
