• What is the cause and solution for SAP error message LTR_MODEL_APPL102 - Transparent usage &1-&2 is not type compatible ?

  The SAP error message LTR_MODEL_APPL102 indicates that there is a type compatibility issue with the transparent usage of a certain object in the context of SAP Landscape Transformation (SLT) or Data Replication. This error typically arises when there is a mismatch between the data types of the source and target fields in the data model.
  Cause:
  
  
  Data Type Mismatch: The most common cause of this error is that the data types of the fields in the source system do not match the data types of the corresponding fields in the target system. For example, a field in the source might be defined as an integer, while the corresponding field in the target is defined as a string.
  
  
  Field Length Issues: Sometimes, even if the data types are the same, the length of the fields may differ, leading to compatibility issues.
  
  
  Incompatible Structures: If you are trying to replicate a structure or table that has been modified (e.g., added or removed fields), it can lead to this error.
  
  
  Incorrect Mapping: If there is a manual mapping of fields that does not respect the data types, this can also trigger the error.
  
  
  Solution:
  
  
  Check Data Types: Review the data types of the fields in both the source and target systems. Ensure that they are compatible. You can do this by checking the data dictionary (SE11) for both systems.
  
  
  Adjust Field Lengths: If the data types are the same but the lengths differ, consider adjusting the lengths in the target system to match those in the source system.
  
  
  Update Replication Model: If there have been changes to the source structure, update the replication model in SLT to reflect these changes. You may need to reconfigure the model to ensure that it aligns with the current structure of the source.
  
  
  Field Mapping: If you are using a custom mapping, ensure that the mappings respect the data types and lengths. You may need to adjust the mapping logic to ensure compatibility.
  
  
  Recreate the Replication Setup: In some cases, it may be easier to delete the existing replication setup and recreate it from scratch, ensuring that all configurations are correct.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to SLT and data replication for any specific guidelines or known issues related to your version of SAP.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like SLT for Landscape Transformation, SE11 for Data Dictionary, and SE80 for Object Navigator to investigate and resolve the issue.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional troubleshooting steps.
  SLT Configuration: Familiarize yourself with SLT configuration settings, as they can impact how data types are handled during replication.
  
  If the issue persists after following these steps, consider reaching out to SAP support for further assistance, providing them with detailed information about the error and the steps you have already taken.
