• What is the cause and solution for SAP error message /BCV/QRM420 - Query &1: Primary field &3 in join crit. &2 is not of type 'Output' ?

  The SAP error message /BCV/QRM420 indicates an issue related to the query definition in the SAP Query tool, specifically concerning the join criteria used in the query. The error message states that a primary field in the join condition is not of the expected type 'Output'. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Field Type Mismatch: The primary field specified in the join condition is not defined as an 'Output' field in the query. In SAP Query, fields used in join conditions must be output fields to ensure that they can be properly processed and displayed in the results.
  Incorrect Query Configuration: The query may have been configured incorrectly, leading to the selection of a field that is not suitable for the join operation.
  Data Source Issues: The data source or underlying table may not have the expected field types, or there may be a misconfiguration in the data model.
  
  Solution:
  
  
  Check Field Definitions:
  
  Go to the query definition and check the field settings for the primary field mentioned in the error message.
  Ensure that the field is marked as an 'Output' field. If it is not, you will need to change its settings.
  
  
  
  Modify Join Criteria:
  
  Review the join criteria in the query. If the primary field cannot be changed to an 'Output' field, consider using a different field that meets the requirements for the join.
  
  
  
  Recreate the Query:
  
  If the query is complex and difficult to troubleshoot, consider recreating the query from scratch, ensuring that all fields used in join conditions are correctly defined as output fields.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for guidance on configuring queries and understanding field types.
  
  
  
  Testing:
  
  After making changes, test the query to ensure that it runs without errors and returns the expected results.
