  The SAP error message LTR_MODEL_APPL093 ("Assign complete primary or secondary key") typically occurs in the context of SAP's Landscape Transformation (SLT) or Data Replication processes. This error indicates that there is an issue with the key assignment in the data model, which is essential for ensuring that data can be uniquely identified and replicated correctly.
  Cause:
  
  
  Incomplete Key Assignment: The error usually arises when the primary or secondary key fields required for the data model are not fully defined. This means that either:
  
  Not all fields that should be part of the key are included.
  The key fields are not properly configured in the data model.
  
  
  
  Data Model Configuration Issues: There may be inconsistencies or misconfigurations in the data model setup, such as:
  
  Missing fields in the source or target tables.
  Incorrect mapping of fields in the data model.
  
  
  
  Data Type Mismatches: If the data types of the key fields in the source and target systems do not match, it can lead to this error.
  
  
  Solution:
  
  
  Check Key Field Configuration:
  
  Go to the data model configuration in the SLT or relevant transaction.
  Ensure that all necessary fields are included in the primary or secondary key definition.
  Verify that the key fields are correctly mapped to the corresponding fields in the source and target tables.
  
  
  
  Review Data Model:
  
  Open the data model in the SLT configuration and check for any missing or incorrectly defined fields.
  Ensure that the data model reflects the correct structure of the source and target tables.
  
  
  
  Data Type Verification:
  
  Check the data types of the key fields in both the source and target systems.
  Ensure that they match and are compatible.
  
  
  
  Reassign Keys:
  
  If necessary, reassign the keys in the data model and save the changes.
  After making changes, you may need to regenerate the data model or restart the replication process.
