GZ031 - Details

• 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:
