• What is the cause and solution for SAP error message AD355 - Nametab generated; adjust the C structures ?

  The SAP error message AD355, which states "Nametab generated; adjust the C structures," typically occurs during the generation of the name table for ABAP programs or function modules. This error indicates that there is a mismatch or inconsistency between the ABAP data dictionary definitions and the generated C structures that are used for the runtime environment.
  Cause:
  
  Changes in Data Dictionary: If there have been recent changes to the data dictionary (like changes to tables, views, or data elements), the generated C structures may not be in sync with the current definitions.
  Inconsistent Naming: If there are inconsistencies in naming conventions or if the naming conventions have changed, it can lead to this error.
  Transport Issues: If objects have been transported between systems (e.g., from development to quality assurance), and the transport did not include all necessary objects, it can lead to inconsistencies.
  System Upgrades: After an upgrade, there may be changes in the underlying structures that require adjustments.
  
  Solution:
  
  Regenerate the Name Table: You can regenerate the name table by executing the transaction code SE11 (Data Dictionary) and then selecting the relevant object. After that, you can choose to regenerate the name table.
  Check for Inconsistencies: Use transaction SE14 (Database Utility) to check for inconsistencies in the database and correct them.
  Adjust C Structures: If you have access to the ABAP source code, you may need to adjust the C structures manually. This usually involves checking the definitions in the data dictionary and ensuring they match the expected structures.
  Transport Requests: Ensure that all relevant transport requests have been properly imported and that there are no missing objects.
  Clear Buffer: Sometimes, clearing the buffer can help resolve issues related to outdated structures. You can do this using transaction code /n/SM12 (to delete lock entries) and /n/SM21 (to check system logs).
