• What is the cause and solution for SAP error message RSDA402 - Field &1 must be in drilldown when sorting by primary key ?

  The SAP error message RSDA402 indicates that there is an issue with the sorting of data in a query or report, specifically when using a primary key. The message states that a certain field (denoted by &1) must be included in the drilldown when sorting by the primary key. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) queries.
  Cause:
  The error is caused by the following reasons:
  
  Field Not in Drilldown: The field that you are trying to sort by is not included in the drilldown structure of the query. In SAP BW, when you sort data by a primary key, all fields that are part of the primary key must be included in the drilldown.
  Query Design: The query might be designed in such a way that it does not allow sorting on certain fields unless they are part of the drilldown.
  Aggregation Issues: If the query is aggregating data, it may require certain fields to be present in the drilldown to maintain the integrity of the data being displayed.
  
  Solution:
  To resolve the RSDA402 error, you can take the following steps:
  
  
  Modify the Query:
  
  Open the query in the Query Designer.
  Ensure that the field mentioned in the error message (&1) is included in the drilldown area of the query.
  If it is not included, add it to the drilldown.
  
  
  
  Check the Primary Key:
  
  Verify the primary key fields of the InfoObject or InfoProvider you are using in the query.
  Ensure that all fields that are part of the primary key are included in the drilldown.
  
  
  
  Adjust Sorting Options:
  
  If you do not need to sort by the primary key, consider changing the sorting options in the query settings to avoid this error.
  
  
  
  Test the Query:
  
  After making the necessary changes, execute the query again to see if the error persists.
