• What is the cause and solution for SAP error message MH028 - SELSTATUS_RT must be specified to read the reference ?

  The SAP error message MH028, which states "SELSTATUS_RT must be specified to read the reference," typically occurs in the context of Material Management (MM) or Production Planning (PP) modules when there is an issue with the selection status of a reference document or data.
  Cause:
  The error is generally caused by one of the following reasons:
  
  Missing Selection Status: The system requires a specific selection status (SELSTATUS_RT) to be defined in order to read the reference data. If this status is not provided, the system cannot proceed with the operation.
  Configuration Issues: There may be a configuration issue in the system where the selection status is not properly set up or is missing in the relevant customizing settings.
  Data Integrity Issues: There could be issues with the data integrity in the database, where the reference data is not correctly linked or is incomplete.
  
  Solution:
  To resolve the MH028 error, you can take the following steps:
  
  
  Check Input Parameters: Ensure that the input parameters for the transaction or function module you are using include the required SELSTATUS_RT field. This may involve modifying the input data or the program logic to include this parameter.
  
  
  Review Configuration: 
  
  Go to the relevant customizing settings in SAP (transaction SPRO) and check the configuration for the selection status related to the specific process you are working on (e.g., material documents, production orders).
  Ensure that the selection status is defined and correctly mapped to the relevant reference data.
  
  
  
  Debugging: If you have access to debugging tools, you can set breakpoints in the relevant function modules or programs to see where the error is triggered and what values are being passed. This can help identify if the SELSTATUS_RT is being set correctly.
  
  
  Consult Documentation: Check the SAP documentation or notes related to the specific transaction or process you are working with. There may be specific notes or updates that address this error.
  
  
  Contact SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. Provide them with the details of the error, the context in which it occurs, and any steps you have already taken to troubleshoot.
