  Cause:
  This error usually arises due to a mismatch between the data types or formats defined for a characteristic and its corresponding check table. Common causes include:
  
  Data Type Mismatch: The data type of the characteristic (e.g., CHAR, NUMC, DATS) does not match the data type of the field in the check table.
  Length Mismatch: The length of the characteristic does not match the length of the corresponding field in the check table.
  Inconsistent Definitions: Changes made to the characteristic or check table definitions that have not been synchronized properly.
  Transport Issues: If the characteristic or check table was transported from one system to another, there may be inconsistencies in the definitions.
  
  Solution:
  To resolve the C1159 error, you can follow these steps:
  
  
  Check Data Types: Verify that the data types of the characteristic and the check table field are the same. You can do this by checking the definitions in the Data Dictionary (SE11).

  Adjust Check Table: If the check table is incorrect, you may need to modify it to match the characteristic's definition.
  
  
  Transport Consistency: If the issue arose after a transport, ensure that all related objects were transported correctly and are consistent across systems.
  
  
  Activate Objects: After making changes, ensure that you activate both the characteristic and the check table to apply the changes.
