• What is the cause and solution for SAP error message CNV_PE091 - Structural mapping &1 has no item, but parameter mapping &3 refers to it ?

  The SAP error message CNV_PE091 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is a structural mapping defined in the migration project that does not have any associated items, yet there is a parameter mapping that references this empty structural mapping.
  Cause:
  
  Missing Items in Structural Mapping: The structural mapping defined in the migration project does not have any items associated with it. This can happen if the mapping was not properly configured or if the items were inadvertently deleted.
  Incorrect Parameter Mapping: The parameter mapping is trying to reference a structural mapping that is not properly set up, leading to inconsistencies in the migration configuration.
  Configuration Errors: There may be errors in the configuration of the migration project, such as incorrect references or missing definitions.
  
  Solution:
  
  Check Structural Mapping: Go to the migration project and check the structural mapping referenced in the error message. Ensure that it has the necessary items defined. If not, you may need to add the required items.
  Review Parameter Mapping: Look at the parameter mapping that is causing the issue. Ensure that it correctly references a valid structural mapping that has items associated with it.
  Reconfigure Mappings: If you find any discrepancies, reconfigure the mappings to ensure that all references are valid and that structural mappings have the necessary items.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using to ensure that you are following the correct procedures for setting up mappings.
  Testing: After making changes, test the migration process again to see if the error persists.
