• What is the cause and solution for SAP error message CM_SUB_MLI001 - An inheriting spec. cannot at same time be a spec. that passes on data ?

  The SAP error message CM_SUB_MLI001 indicates that there is a conflict in the configuration of a specification in the SAP system, particularly in the context of the Classification Management (CM) module. This error typically arises when a specification is defined as both an inheriting specification and a specification that passes on data, which is not allowed.
  Cause:
  
  Inheriting Specification: This type of specification is meant to inherit characteristics from another specification. It does not hold its own data but rather derives its attributes from a parent specification.
  Passing on Data: A specification that passes on data is expected to hold its own data and can be used to transfer data to other specifications or objects.
  Conflict: The error occurs because the system does not allow a specification to serve both roles simultaneously. A specification cannot inherit from another while also being responsible for passing on its own data.
  
  Solution:
  To resolve this error, you need to review the configuration of the specifications involved and make adjustments to ensure that a specification is either an inheriting specification or a specification that passes on data, but not both. Here are the steps you can take:
  
  
  Review Specification Settings:
  
  Go to the specification in question and check its settings.
  Determine if it is set as an inheriting specification and if it is also marked to pass on data.
  
  
  
  Modify Specification Type:
  
  If the specification is intended to inherit from another, ensure it is not set to pass on data. You may need to change its type or configuration.
  Conversely, if the specification is meant to pass on data, remove the inheriting designation.
  
  
  
  Check Parent Specifications:
  
  If the specification is inheriting from a parent, ensure that the parent specification is correctly configured and does not have conflicting settings.
  
  
  
  Test Changes:
  
  After making the necessary adjustments, test the changes to ensure that the error no longer occurs.
