How To Fix 0K547 - Field &1 has different data type (&2) and internal type (&3)

SAP Error Message - Details

• Message type: E = Error

• Message class: 0K - Messages for "General List Modules"

• Message number: 547

• Message text: Field &1 has different data type (&2) and internal type (&3)

What causes this issue?

In the field catalog, data type &2 and internal type &3 were assigned
to field &1. These types are not identical.

System Response

This may lead to some functions being not executed properly.

How to fix this error?

Correct this error immediately.
When the field catalog is set up, only DATATYPE must be filled. You do
not need to fill INTTYPE since INTTYPE is derived from the DATATYPE
passed.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message 0K547 - Field &1 has different data type (&2) and internal type (&3) ?

  The SAP error message 0K547 indicates a data type mismatch in a field during processing. Specifically, it means that the field specified (denoted as &1) has a different data type than what is expected internally (denoted as &2 for the expected type and &3 for the actual internal type). This error typically occurs in ABAP programs, data dictionary objects, or when working with data transfer between different systems or modules.
  Cause:
  
  Data Type Mismatch: The field in question is defined with a certain data type in the database or data dictionary, but the program or function module is trying to use it with a different data type.
  Inconsistent Definitions: The field might have been changed in the data dictionary (e.g., changed from CHAR to NUMC) without updating all related programs or structures.
  Incorrect Mapping: When transferring data between different systems or modules, the mapping of fields may not align correctly, leading to type mismatches.
  Field Length Issues: Sometimes, the length of the field may also cause issues if the internal representation does not match the expected length.
  
  Solution:
  
  Check Data Dictionary: Verify the data type of the field in the data dictionary (SE11) and ensure it matches the expected type in the program or function module.
  Update Program/Function Module: If the data type has changed, update the relevant ABAP code to ensure it uses the correct data type.
  Adjust Data Mapping: If the error occurs during data transfer, check the mapping of fields between the source and target systems to ensure they align correctly.
  Use Type Casting: If necessary, use type casting in ABAP to convert the data to the expected type before processing.
  Check for Changes: If the error started occurring after a recent change, review the changes made to the data dictionary or related programs to identify any inconsistencies.
  
  Related Information:
  
  Transaction Codes: Use SE11 to check the data dictionary, SE80 for object navigation, and SE37 for function modules.
  Debugging: Use the ABAP debugger to trace the execution and identify where the mismatch occurs.
  Documentation: Review SAP notes and documentation related to data types and field definitions for best practices.
  Testing: After making changes, thoroughly test the program to ensure that the error is resolved and that no new issues have been introduced.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
