• What is the cause and solution for SAP error message EZ551 - DDIC type &1 is already used in form class &2 (form level &3) ?

  The SAP error message EZ551 indicates that there is a conflict with the Data Dictionary (DDIC) type being used in a form class. Specifically, it means that the DDIC type you are trying to use is already in use in another form class at the specified form level. This can occur in various scenarios, particularly when working with Smart Forms or Adobe Forms in SAP.
  Cause:
  
  Duplicate Usage: The DDIC type is already defined or used in another form class, which leads to a conflict when you try to use it again in a different context.
  Form Class Hierarchy: If you are working with a hierarchy of form classes, the same DDIC type might be inherited or referenced in multiple places, causing this error.
  Incorrect Form Class Configuration: There might be an issue with how the form classes are configured or structured, leading to overlapping definitions.
  
  Solution:
  
  Check Form Class Definitions: Review the form classes involved to identify where the DDIC type is being used. Ensure that the type is not redundantly defined in multiple places.
  Modify Form Class: If possible, modify the form class that is causing the conflict. You may need to change the DDIC type being used or refactor the form class to avoid the conflict.
  Use Unique DDIC Types: Ensure that each form class uses unique DDIC types where necessary. If the same type is needed, consider creating a new type or using a different approach to reference the existing type.
  Review Inheritance: If your form classes are inheriting from a base class, check the base class for the DDIC type definition and ensure that it is not causing conflicts in derived classes.
  Transport Requests: If this issue arises after a transport, ensure that all related objects are included in the transport request to avoid inconsistencies.
