  The SAP error message /PLMI/AL_GSS_R2MR_SU042 indicates that a Material Bill of Materials (BOM) alternative is mandatory for creating a synchronization unit in the context of SAP's Advanced Planning and Optimization (APO) or similar modules. This error typically arises when the system requires a specific BOM alternative to proceed with the creation of a synchronization unit, but it is either missing or not specified.
  Cause:
  
  Missing BOM Alternative: The system expects a BOM alternative to be defined for the material in question, but it is not available.
  Incorrect Configuration: The configuration settings for the material or the synchronization unit may not be set up correctly, leading to the requirement for a BOM alternative.

  Solution:
  
  
  Check BOM Alternatives:
  
  Navigate to the BOM management transaction (e.g., CS03) and check if the BOM alternatives for the material are defined.
