• What is the cause and solution for SAP error message LTR_MODEL_APPL095 - Secondary key is used but not all of its fields are assigned ?

  The SAP error message LTR_MODEL_APPL095 indicates that a secondary key is being used in a data model or application, but not all of the fields that are part of that secondary key have been assigned values. This typically occurs in the context of data modeling or when working with data structures in SAP applications, such as SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error is caused by the following scenarios:
  
  Incomplete Field Assignment: When defining a secondary key, all fields that are part of that key must be populated with values. If any field is left unassigned or null, the system will raise this error.
  Data Model Configuration: The configuration of the data model may not be correctly set up to handle the secondary key, leading to missing assignments.
  Data Loading Issues: If data is being loaded into a model and not all required fields for the secondary key are included in the data source, this error can occur.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Field Assignments:
  
  Review the data model or application where the error is occurring.
  Ensure that all fields that are part of the secondary key are assigned values. This may involve checking the source data or the transformation logic that populates these fields.
  
  
  
  Review Data Source:
  
  If you are loading data from an external source, verify that the data source includes all necessary fields for the secondary key.
  Make sure that the data extraction process is correctly configured to pull in all required fields.
  
  
  
  Adjust Data Model Configuration:
  
  If applicable, check the configuration of the data model to ensure that it is set up correctly to handle the secondary key.
  You may need to modify the model to include additional fields or adjust the key definition.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the data load or model execution again to ensure that the error is resolved.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on handling secondary keys in your particular context (e.g., SAP BW, SAP HANA).
  
  
  
  Related Information:
