• What is the cause and solution for SAP error message FDT_CORE698 - No change allowed (no change of t- or s-table objects) ?

  The SAP error message FDT_CORE698 indicates that a change is not allowed for certain types of database objects, specifically T-tables (transparent tables) and S-tables (structure tables). This error typically arises in the context of using the SAP Fiori Design Tools or when working with the SAP FDT (Form Data Tool) framework, which is used for managing forms and data in SAP applications.
  Cause:
  The error occurs due to the following reasons:
  
  Modification Restrictions: T-tables and S-tables are generally not meant to be modified directly in certain contexts, especially when they are part of a standard SAP delivery. This is to maintain data integrity and consistency.
  System Configuration: The system may be configured to prevent changes to these objects to protect the underlying data model.
  Transport Layer Issues: If you are trying to transport changes that involve T-tables or S-tables, the system may restrict these changes to avoid inconsistencies.
  
  Solution:
  To resolve the FDT_CORE698 error, consider the following steps:
  
  
  Check Object Type: Ensure that you are not trying to modify a T-table or S-table directly. If you need to make changes, consider creating a custom table or structure instead.
  
  
  Use Custom Objects: If you need to extend functionality, create Z-tables (custom tables) or Z-structures (custom structures) that can be modified without restrictions.
  
  
  Review Authorizations: Ensure that you have the necessary authorizations to make changes to the objects you are working with. Sometimes, lack of proper authorizations can lead to such errors.
  
  
  Consult Documentation: Review the SAP documentation related to the FDT and the specific objects you are working with to understand the limitations and best practices.
  
  
  Contact SAP Support: If you believe that the error is occurring inappropriately or if you need further assistance, consider reaching out to SAP Support for guidance.
