How To Fix AD735 - Foreign key &-& (flag as a semantic foreign key)

SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 735

• Message text: Foreign key &-& (flag as a semantic foreign key)

What causes this issue?

A foreign key must be flagged either as a semantic foreign key or as a
screen foreign key. In the case of a screen foreign key, a check is
always made for any input to the screen through the mask processor.
This foreign key is always found with internal tables (without under-
lying database table) and also with foreign keys that are contained
completely within a semantic foreign key. Semantic foreign keys are
part of the data model and are further identified by their dependency
factor and cardinality. Apart from the check on screen entry, they
imply referential integrity conditions.

System Response

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

How to fix this error?

Please flag this foreign key as semantic foreign key or screen foreign
key.

• What is the cause and solution for SAP error message AD735 - Foreign key &-& (flag as a semantic foreign key) ?

  The SAP error message AD735, which indicates a foreign key issue, typically arises when there is a problem with the foreign key relationship defined in the data model. This error message is often related to semantic checks in the context of data integrity and consistency.
  Cause:
  The error message AD735 usually occurs due to one of the following reasons:
  
  Missing Foreign Key Relationship: The foreign key relationship that is expected is not defined in the database table or is incorrectly defined.
  Data Inconsistency: The data being inserted or updated does not comply with the foreign key constraints, meaning that the referenced key does not exist in the parent table.
  Semantic Issues: The foreign key is flagged as a semantic foreign key, which means that it is expected to have a logical relationship with another table, but this relationship is not being satisfied.
  
  Solution:
  To resolve the AD735 error, you can take the following steps:
  
  
  Check Foreign Key Definition:
  
  Go to the Data Dictionary (transaction SE11) and check the foreign key definitions for the relevant tables.
  Ensure that the foreign key relationship is correctly defined and that the referenced table and field exist.
  
  
  
  Validate Data:
  
  Check the data you are trying to insert or update. Ensure that the values for the foreign key fields correspond to existing records in the parent table.
  If you are inserting new records, make sure that the parent records are created before the child records.
  
  
  
  Review Semantic Relationships:
  
  If the foreign key is flagged as a semantic foreign key, review the business logic to ensure that the relationship makes sense and is being enforced correctly.
  You may need to adjust the application logic or data flow to ensure that the foreign key constraints are met.
  
  
  
  Debugging:
  
  If the issue persists, consider using transaction codes like SE37 (Function Module) or SE80 (Object Navigator) to debug the program or function module that is causing the error.
  Check for any custom code that might be interfering with the standard behavior.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific error message for any additional insights or updates that may apply to your version of SAP.
