• What is the cause and solution for SAP error message FDT_EXPRESSIONS776 - Result data object is incompatible with the result of table operation ?

  The SAP error message FDT_EXPRESSIONS776 indicates that there is an incompatibility between the result data object and the result of a table operation in the context of SAP's Flexible Data Model (FDT). This typically occurs when you are working with expressions or calculations that involve data from tables, and the expected data types or structures do not match.
  Cause:
  
  
  Data Type Mismatch: The result data object may have a different data type than what is being returned from the table operation. For example, if the table operation returns a numeric value but the result data object is defined as a string, this error will occur.
  
  
  Structure Incompatibility: If the result of the table operation is a complex structure (like a table or a record) and the result data object is defined as a simple type (like a single value), this can lead to incompatibility.
  
  
  Incorrect Mapping: If there is a mapping issue where the fields in the result data object do not correspond correctly to the fields being returned from the table operation.
  
  
  Expression Logic Errors: If the expression logic used to derive the result is flawed or does not align with the expected output.
  
  
  Solution:
  
  
  Check Data Types: Review the data types of both the result data object and the output of the table operation. Ensure they are compatible. You may need to change the data type of the result data object or adjust the table operation to return a compatible type.
  
  
  Review Structure: If the result of the table operation is a complex structure, ensure that the result data object is also defined to handle that structure. You may need to create a new data object that matches the expected structure.
  
  
  Adjust Mapping: Verify the mapping between the fields in the result data object and the fields returned from the table operation. Ensure that all fields are correctly aligned.
  
  
  Debug Expression Logic: If you are using expressions to derive the result, debug the logic to ensure it is correctly formulated and that it aligns with the expected output.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the specific functions or operations you are using, as they may provide insights into common pitfalls and best practices.
  
  
  Related Information:
