• What is the cause and solution for SAP error message AD286 - Check table & is also foreign key table ?

  The SAP error message AD286 indicates that there is an issue with a check table that is also defined as a foreign key table. This typically occurs during the process of defining or modifying a database table in the Data Dictionary (SE11) or when trying to activate a table that has foreign key relationships.
  Cause:
  The error arises when:
  
  A check table is being used as a foreign key table, which is not allowed in SAP. A check table is meant to validate entries in a field, while a foreign key table is used to establish a relationship between two tables.
  There may be inconsistencies in the definitions of the tables or their relationships.
  
  Solution:
  To resolve the AD286 error, you can follow these steps:
  
  
  Review Table Definitions:
  
  Go to transaction SE11 and check the definitions of the tables involved. Ensure that the check table is not being used as a foreign key table.
  
  
  
  Modify Foreign Key Relationships:
  
  If the check table is incorrectly defined as a foreign key table, you need to remove or modify the foreign key relationship. This can be done in the table definition where the foreign key is defined.
  
  
  
  Adjust Check Table Usage:
  
  If you need to use a check table, ensure that it is only used for validation purposes and not as a foreign key. You may need to create a separate table for foreign key relationships if necessary.
  
  
  
  Activate Tables:
  
  After making the necessary changes, try to activate the tables again. Ensure that there are no other errors present.
  
  
  
  Check Dependencies:
  
  If the error persists, check for any dependencies or other tables that might be causing the issue. Sometimes, other related tables may also need to be adjusted.
