• What is the cause and solution for SAP error message GZ031 - Only batch-input ('B') or ODC ('O') can be requested ?

  The SAP error message GZ031 ("Only batch-input ('B') or ODC ('O') can be requested") typically occurs when there is an issue with the processing mode specified for a transaction or function module in SAP. This error indicates that the system is expecting a specific type of processing mode (either batch input or ODC) but is receiving a different one.
  Cause:
  
  Incorrect Processing Mode: The error usually arises when a transaction is called with an invalid processing mode. For example, if a program or transaction is trying to execute in a mode other than 'B' (Batch Input) or 'O' (Online Data Capture), the system will throw this error.
  Configuration Issues: There may be configuration settings in the system that are not aligned with the expected processing modes.
  Custom Code: If there is custom ABAP code that is calling a transaction or function module with an incorrect parameter, it can lead to this error.
  
  Solution:
  
  Check Processing Mode: Ensure that the processing mode being used is either 'B' for Batch Input or 'O' for Online Data Capture. If you are using a custom program or transaction, verify the parameters being passed.
  Review Custom Code: If the error is occurring in a custom program, review the code to ensure that the correct processing mode is being specified when calling the transaction or function module.
  Transaction Configuration: Check the configuration settings for the transaction in question. Ensure that it is set up to accept the desired processing mode.
  Debugging: If the issue persists, consider debugging the program or transaction to trace where the incorrect processing mode is being set or passed.
  Consult Documentation: Refer to SAP documentation or notes related to the specific transaction or function module to understand the expected parameters and processing modes.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific transaction or function module you are working with.
  Transaction Codes: Familiarize yourself with the transaction codes involved in the process to better understand their expected behavior.
