• What is the cause and solution for SAP error message ADT_DATAPREVIEW_MSG020 - Data preview is not available for abstract entities ?

  The SAP error message ADT_DATAPREVIEW_MSG020 indicates that data preview is not available for abstract entities in the context of SAP's ABAP Development Tools (ADT). This typically occurs when you are trying to preview data for an abstract entity type, which is not directly instantiable or does not have a concrete implementation.
  Cause:
  
  Abstract Entity: The entity you are trying to preview is defined as an abstract entity in the ABAP Dictionary. Abstract entities are meant to serve as base types for other entities and cannot be instantiated on their own.
  Lack of Concrete Implementation: Since abstract entities do not have a direct representation in the database, there is no data to preview.
  
  Solution:
  
  Use Concrete Entities: Instead of trying to preview data for the abstract entity, identify the concrete entities that inherit from the abstract entity. You can then preview data for those concrete entities.
  Check Inheritance: Review the ABAP Dictionary to find out which concrete entities are derived from the abstract entity. You can do this by checking the "Inheritance" tab in the entity definition.
  Data Preview on Concrete Entities: Once you have identified the concrete entities, perform the data preview on those instead.
  
  Related Information:
  
  ABAP Dictionary: Familiarize yourself with the ABAP Dictionary, where you can define and manage database objects, including abstract and concrete entities.
  Entity Relationships: Understanding the relationships between abstract and concrete entities can help in navigating the data model effectively.
  Documentation: Refer to SAP documentation or help resources for more information on abstract entities and their usage in ABAP.
