• What is the cause and solution for SAP error message SWF_FLEX_BRF018 - Given database view '&1' has no key field besides the client ?

  The SAP error message SWF_FLEX_BRF018 indicates that there is an issue with a database view that is being used in the context of Business Rule Framework (BRF) or Workflow. Specifically, the error states that the database view specified (represented by &1) does not have a key field defined other than the client field. This can lead to issues when the system tries to access or manipulate data from that view, as it requires a unique identifier to work correctly.
  Cause:
  
  Missing Key Fields: The database view does not have a primary key or unique key field defined, which is necessary for the system to uniquely identify records.
  Client Field: The only key field present is the client field, which is not sufficient for the operations that the BRF or Workflow is trying to perform.
  View Definition: The way the database view is defined may not meet the requirements for the BRF or Workflow to function properly.
  
  Solution:
  
  
  Modify the Database View:
  
  Access the definition of the database view in the ABAP Dictionary (transaction SE11).
  Ensure that the view includes at least one additional key field besides the client field. This could be a combination of fields that together form a unique identifier for the records in the view.

  Check Dependencies:
