How To Fix AD733 - Foreign key &-& (use cardinality 1 : N or 1 : CN with 'TEXT')

SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 733

• Message text: Foreign key &-& (use cardinality 1 : N or 1 : CN with 'TEXT')

What causes this issue?

In the case of a text-foreign key, only one of
the <DS:TX.MK-CARD> cardinalities</> '1:N' or '1:CN' can be correct.
It must be possible to create text in several languages for each
object, but there may be no texts for which the object is not entered
in the check table.

• What is the cause and solution for SAP error message AD733 - Foreign key &-& (use cardinality 1 : N or 1 : CN with 'TEXT') ?

  The SAP error message AD733 typically indicates an issue with the foreign key relationship in a database table or structure. This error arises when the cardinality of the foreign key relationship is not correctly defined, particularly when it involves a text field.
  Cause:
  The error message "Foreign key &-& (use cardinality 1 : N or 1 : CN with 'TEXT')" suggests that the foreign key relationship you are trying to establish is not compatible with the data type or cardinality defined in the database schema. Specifically, it indicates that:
  
  You are trying to create a foreign key relationship with a text field (which is usually a long text or a string).
  The cardinality of the relationship is not set to either 1:N (one-to-many) or 1:CN (one-to-conditional-many), which are the only valid cardinalities for foreign keys involving text fields.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Data Model: Review the data model to ensure that the foreign key relationship is correctly defined. Make sure that the fields involved in the foreign key relationship are compatible in terms of data type and cardinality.
  
  
  Adjust Cardinality: If you are defining a foreign key relationship with a text field, ensure that the cardinality is set to either 1:N or 1:CN. This can usually be done in the data dictionary (SE11) or the relevant table maintenance transaction.
  
  
  Modify the Field Type: If possible, consider changing the field type of the foreign key to a more appropriate type that allows for a different cardinality, if that aligns with your data model requirements.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on defining foreign keys and cardinalities, especially when dealing with text fields.
  
  
  Testing: After making the necessary changes, test the foreign key relationship to ensure that it works as expected without triggering the error message.
  
  
  Related Information:
  
  Data Dictionary (SE11): This is the transaction code in SAP where you can view and modify database tables, including foreign key relationships.
  Cardinality Definitions:
  
  1:N (One-to-Many): One record in the primary table can relate to multiple records in the foreign table.
  1:CN (One-to-Conditional-Many): Similar to one-to-many but allows for conditional relationships based on certain criteria.
  
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  
  By following these steps, you should be able to resolve the AD733 error and establish the foreign key relationship correctly.
