How To Fix TR233 - Foreign key table & has delivery class 'C'

SAP Error Message - Details

• Message type: E = Error

• Message class: TR - Change and Transport System

• Message number: 233

• Message text: Foreign key table & has delivery class 'C'

What causes this issue?

You attempted to allocate a name range for field "&V3&" in table "&V2&".
Table "&V2&" has a check table "&V1&" that belongs to the
delivery class "C".
A table that belongs to delivery class "C" is a customizing table.
Maintenance is only carried out by the customer, so no SAP import takes
place.
Under these circumstances, no key can be transported from table "&V2&"
because no information on the values in field "&V3&" is passed on to the
customer.

System Response

Name ranges can only be allocated to tables belonging to the delivery
classes "E" or "G".

How to fix this error?

Check whether table "&V2&" should also belong to delivery class
"C", or whether table "&V1&" should not belong to delivery class "C".

• What is the cause and solution for SAP error message TR233 - Foreign key table & has delivery class 'C' ?

  The SAP error message TR233 indicates that there is an issue with a foreign key relationship in the database. Specifically, it states that the foreign key table has a delivery class 'C'. This means that the table is intended for customer-specific data and is not meant to be transported between systems (e.g., from development to production).
  Cause:
  The error typically arises when you attempt to create or modify a foreign key relationship that references a table with a delivery class of 'C'. In SAP, delivery classes determine how data is handled during transport. A delivery class 'C' indicates that the table is not transportable, which can lead to issues when trying to establish foreign key constraints that involve such tables.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Review Foreign Key Relationships: Check the foreign key relationships you are trying to create or modify. Ensure that they do not reference tables with a delivery class of 'C'.
  
  
  Change Delivery Class: If it is appropriate for your business case, you could consider changing the delivery class of the foreign key table to a transportable class (like 'A' or 'B'). However, this should be done with caution and typically requires a thorough understanding of the implications, as it may affect how data is managed across different environments.
  
  
  Use Alternative Tables: If changing the delivery class is not feasible, consider using alternative tables that are transportable and can fulfill the same purpose without causing the error.
  
  
  Consult Documentation: Review SAP documentation or consult with your SAP Basis or ABAP team to understand the implications of changing delivery classes and to ensure that you are following best practices.
  
  
  Check for Custom Development: If this error arises during custom development, ensure that the custom tables and their relationships are designed correctly, adhering to SAP's guidelines for transportable objects.
  
  
  Related Information:
  
  
  Delivery Classes: In SAP, delivery classes define how tables are treated in terms of transport and data management. Common delivery classes include:
  
  A: Application table (transportable)
  B: Pool table (transportable)
  C: Customizing table (not transportable)
  D: System table (not transportable)
  
  
  
  Foreign Key Constraints: Foreign key constraints are used to maintain referential integrity between tables. When designing database schemas in SAP, it's important to ensure that all referenced tables are compatible in terms of transportability.
  
  
  SAP Notes: Check SAP Notes for any specific guidance or updates related to this error message, as SAP frequently updates its knowledge base with solutions to common issues.
