How To Fix E2211 - Cardinality C:m is not allowed for key fields of a text table

SAP Error Message - Details

• Message type: E = Error

• Message class: E2 - DE Data Dictionary

• Message number: 211

• Message text: Cardinality C:m is not allowed for key fields of a text table

The foreign key field type specified for the foreign key fields was
'key fields of a text table'.
Thus, the condition applies that the dependent table is a
language-dependent text table for the referenced table. The key of the
text table is composed of the key of the referenced table and a
language key.
There can be no entries in the text table that do not refer to a record
in the check table. Consequently, the left side of the cardinality may
not be C. Only the cardinalities 1 : N and 1 : CN are valid.

• What is the cause and solution for SAP error message E2211 - Cardinality C:m is not allowed for key fields of a text table ?

  The SAP error message E2211, which states "Cardinality C:m is not allowed for key fields of a text table," typically occurs when there is an issue with the definition of a text table in the Data Dictionary (SE11) of SAP. This error is related to the cardinality settings of the key fields in a text table.
  Cause:
  
  
  Incorrect Cardinality Definition: In SAP, text tables are used to store language-dependent texts. The key fields of a text table must have a specific cardinality. The error indicates that the cardinality defined for the key fields is not allowed. Specifically, a text table should have a 1:1 relationship with the main table, meaning that for each entry in the main table, there should be exactly one corresponding entry in the text table.
  
  
  Multiple Key Fields: If you have defined multiple key fields in the text table, and their relationship does not conform to the expected cardinality, this error can occur.
  
  
  Inconsistent Data Model: The data model may be inconsistent, where the relationships between the main table and the text table are not properly defined.
  
  
  Solution:
  
  
  Check Key Fields: Go to the Data Dictionary (SE11) and check the definition of the text table. Ensure that the key fields are defined correctly. Typically, a text table should have a single key field that corresponds to the main table's key.
  
  
  Adjust Cardinality: If you have defined multiple key fields, consider adjusting them to ensure that the cardinality is 1:1. You may need to remove or modify the key fields to comply with the expected structure.
  
  
  Review Relationships: Check the relationships between the main table and the text table. Ensure that the foreign key relationships are correctly defined and that they reflect the intended data model.
  
  
  Recreate the Table: If the table definition is complex and difficult to correct, you may consider recreating the text table with the correct key field definitions and cardinality.
  
  
  Consult Documentation: Refer to SAP documentation or consult with a functional consultant to ensure that the text table is set up according to best practices.
  
  
  Related Information:
  
  Text Tables: Text tables in SAP are used to store descriptions or texts in multiple languages. They are typically linked to a main table through a foreign key relationship.
  Data Dictionary (SE11): This is the transaction code in SAP where you can create and manage database objects, including tables, views, and data elements.
  Cardinality: In database design, cardinality refers to the uniqueness of data values contained in a particular field (attribute) of a table. It defines the relationship between two tables.
  
  By following these steps, you should be able to resolve the E2211 error and ensure that your text table is correctly defined in SAP.
