• What is the cause and solution for SAP error message APO_BAPI355 - Obligatory parameter &1 was not transferred or was transferred blank ?

  The SAP error message APO_BAPI355 indicates that a required parameter (denoted as &1) was either not provided or was provided with a blank value when calling a BAPI (Business Application Programming Interface) in the SAP Advanced Planning and Optimization (APO) module. This error typically occurs when the BAPI is expecting certain mandatory fields to be filled in, and they are either missing or empty.
  Cause:
  
  Missing Mandatory Fields: The BAPI you are trying to call has mandatory fields that must be populated with valid data. If any of these fields are not included in the call, or if they are included but left blank, this error will occur.
  Incorrect Mapping: If you are using a custom program or interface to call the BAPI, there may be an issue with how the parameters are being mapped or passed to the BAPI.
  Data Validation: The data being passed may not meet the validation criteria set by the BAPI, leading to the error.
  
  Solution:
  
  Check BAPI Documentation: Review the documentation for the specific BAPI you are using to identify which parameters are mandatory. Ensure that all required fields are being populated correctly.
  Debugging: If you are using a custom program, debug the code to see what values are being passed to the BAPI. Ensure that all mandatory parameters are being filled with valid data.
  Error Handling: Implement error handling in your code to catch and log any issues when calling the BAPI. This can help you identify which parameter is causing the issue.
  Testing: Test the BAPI call with hardcoded values for the mandatory parameters to ensure that the BAPI itself is functioning correctly. This can help isolate whether the issue is with the BAPI or with how it is being called.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that might address this specific error or provide additional guidance.
