  The SAP error message SADL_EXPOSURE056 indicates that a base view in the context of the SAP Data Access Layer (SADL) is incorrectly defined as a BDEF (Business Definition) based view. This error typically arises when you are trying to expose a base view that is not suitable for the operation you are attempting to perform.
  Cause:
  The error occurs when:
  
  You are trying to expose a base view that is defined as a BDEF, which is not allowed in the context of the operation you are performing.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Base View Definition:
  
  Go to the definition of the base view (the one indicated by &1 in the error message).
  Verify if it is indeed defined as a BDEF. If it is, you will need to change its definition.
  
  
  
  Change the View Type:
  
  If the base view is incorrectly defined as a BDEF, you may need to redefine it as a standard view or another appropriate type that is compatible with the SADL exposure.
  This may involve modifying the underlying data model or the way the view is constructed.
  
  
  
  Review SADL Documentation:
  
  Consult the SAP documentation related to SADL and the specific types of views that can be exposed. This will help you understand the requirements and limitations of the views you are working with.
