• What is the cause and solution for SAP error message DT343 - A proxy view can only be specified for database tables ?

  The SAP error message DT343, which states "A proxy view can only be specified for database tables," typically occurs in the context of Data Dictionary (DDIC) objects in SAP, particularly when working with views and database tables in ABAP.
  Cause:
  This error usually arises when you attempt to create or modify a proxy view that is not based on a database table. Proxy views are intended to provide a way to access data from database tables through a defined interface, and they cannot be created for non-database objects such as structures, internal tables, or other non-database entities.

  Use Appropriate View Types: If you are working with non-database objects, consider using other types of views (like projection views or database views) that are appropriate for your data model.
