• What is the cause and solution for SAP error message LTR_MODEL_APPL074 - Mapping key components do not belong to the target Business Object ?

  The SAP error message LTR_MODEL_APPL074 indicates that there is a mismatch between the mapping key components in your data model and the target Business Object (BO) in the SAP Landscape Transformation (SLT) or SAP Data Services environment. This error typically arises during data replication or transformation processes when the system cannot find the expected key components in the target BO.
  Cause:
  
  Key Component Mismatch: The key components defined in the source system do not match the key components defined in the target Business Object. This could be due to changes in the data model or incorrect configuration.
  Incorrect Mapping: The mapping configuration may not correctly align the source fields with the target fields, leading to discrepancies.
  Data Model Changes: If there have been recent changes to the data model in either the source or target system, it may result in this error if the mappings have not been updated accordingly.
  Missing Key Fields: The target Business Object may be missing required key fields that are expected based on the source data.
  
  Solution:
  
  Verify Mapping Configuration: Check the mapping configuration in the SLT or Data Services environment to ensure that all key components from the source are correctly mapped to the corresponding fields in the target Business Object.
  Update Data Model: If there have been changes to the data model, ensure that the mappings are updated to reflect these changes. This may involve adding or modifying key fields in the target Business Object.
  Check Key Fields: Ensure that all required key fields are present in the target Business Object. If any key fields are missing, you may need to add them to the target model.
  Test with Sample Data: Run a test with a small set of data to see if the error persists. This can help isolate the issue and confirm that the mappings are now correct.
  Consult Documentation: Review SAP documentation or notes related to the specific Business Object and mapping configurations to ensure compliance with best practices.
