• What is the cause and solution for SAP error message /PLMB/BA_SAM155 - Precondition &1 not implemented in precondition class &2 ?

  The SAP error message /PLMB/BA_SAM155 Precondition &1 not implemented in precondition class &2 typically occurs in the context of SAP PLM (Product Lifecycle Management) when a certain precondition check is being executed, but the specific implementation for that precondition is missing or not defined in the specified precondition class.
  Cause:
  
  Missing Implementation: The precondition that is being checked is not implemented in the specified precondition class. This could be due to a missing custom implementation or a standard implementation that has not been activated.
  Configuration Issues: There may be configuration issues in the PLM system that prevent the precondition from being recognized or executed properly.
  Incorrect Precondition Class: The precondition class specified in the error message may not be the correct one for the operation being performed.
  
  Solution:
  
  Check Precondition Class: Verify that the precondition class specified in the error message is correct and that it is intended to handle the precondition being checked.
  Implement Missing Precondition: If the precondition is indeed missing, you may need to implement it. This could involve creating a custom implementation in ABAP or ensuring that the standard implementation is activated.
  Review Configuration: Check the configuration settings in the PLM module to ensure that all necessary settings are in place and that the precondition classes are properly defined.
  Consult Documentation: Refer to SAP documentation or notes related to the specific precondition class and its expected behavior. This may provide insights into what is required for the implementation.
  Debugging: If you have access to the development environment, you can debug the process to see where the precondition check is failing and gather more information about the context of the error.
