  Cause:

  Missing Foreign Key Definition: The foreign key relationship between the field and the check table is not properly defined in the Data Dictionary.
  Inconsistent Data: There may be existing data in the table that does not comply with the foreign key constraints, leading to a violation of referential integrity.

  To resolve this error, you can take the following steps:
  
  
  Check Foreign Key Definition:
