  The SAP error message DMCLG787 indicates that there is a type mismatch between the source object and the target object in a data transfer or data migration process. This error typically occurs in scenarios involving data management, such as Data Migration Cockpit (DMC), Data Services, or other data transfer tools within SAP.
  Cause:
  The error arises when the source object (e.g., a table, view, or data structure) and the target object are not of the same type. This can happen due to several reasons:
  
  Different Object Types: The source and target objects may be of different types (e.g., trying to map a table to a view).
  Incompatible Data Structures: The structure of the source data may not match the expected structure of the target data.
  Incorrect Mapping: The mapping configuration may have been set up incorrectly, leading to a mismatch in data types or structures.
  Version Mismatch: If the source and target systems are on different versions of SAP, there may be discrepancies in object definitions.
  
  Solution:
  To resolve the DMCLG787 error, you can take the following steps:

  Correct Mapping: Review the mapping configuration in your data transfer tool. Ensure that each field in the source is correctly mapped to a corresponding field in the target.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific data transfer tool you are using to understand the requirements for object types and structures.
  
  
  Test with Sample Data: If possible, test the data transfer with a small sample of data to identify any specific issues before attempting a full migration.
