• What is the cause and solution for SAP error message SADL_GW010 - Group by '&1'. Grouping by '&1' is necessary to group by '&2' ?

  The SAP error message SADL_GW010 typically occurs in the context of the SAP ABAP programming environment, particularly when using the SAP Data Access Layer (SADL) for handling data queries. This error indicates that there is a problem with the grouping of data in a query, specifically that the system requires a certain grouping to be performed in order to fulfill the query requirements.
  Cause:
  The error message is triggered when:
  
  You are trying to execute a query that requires grouping by a specific field (denoted as &1 in the error message).
  The query is not correctly grouping by the required field, which is necessary to also group by another field (denoted as &2).
  This often happens when the query is constructed without the necessary aggregation or grouping logic, leading to inconsistencies in the data retrieval process.
  
  Solution:
  To resolve the SADL_GW010 error, you can take the following steps:
  
  
  Review the Query Definition: Check the query definition in your SADL model. Ensure that the fields you are trying to group by are correctly specified.
  
  
  Add Required Grouping: Modify the query to include the necessary grouping by the field &1. This may involve adjusting the SELECT statement or the data model to ensure that the required fields are included in the GROUP BY clause.
  
  
  Check Aggregation Logic: If your query involves aggregation (e.g., SUM, COUNT), ensure that all non-aggregated fields in the SELECT clause are included in the GROUP BY clause.
  
  
  Test the Query: After making the necessary adjustments, test the query again to ensure that it executes without errors.
  
  
  Consult Documentation: If you are unsure about the required fields or the structure of your query, refer to the SAP documentation or the specific guidelines for using SADL.
  
  
  Debugging: If the issue persists, consider using debugging tools to trace the execution of the query and identify where the grouping logic is failing.
