• What is the cause and solution for SAP error message DT311 - Changed foreign key &-& is still used in: ?

  The SAP error message DT311 indicates that a foreign key relationship has been changed, but there are still existing references to that foreign key in the database. This typically occurs when you attempt to modify a foreign key constraint in a way that is not compatible with existing data or relationships.
  
  Cause:
  
  Foreign Key Modification: You may have attempted to change the definition of a foreign key (e.g., changing the referenced table or field) while there are still records in the database that rely on the old foreign key definition.
  Data Integrity Violation: The existing data may violate the new foreign key constraints, meaning that there are records that would no longer be valid if the change were applied.
  Dependent Objects: There may be dependent objects (like views, indexes, or other foreign keys) that are still using the old foreign key definition.
  
  
  Solution:
  
  Identify Dependencies: Use transaction codes like SE11 (Data Dictionary) or SE14 (Database Utility)
