• What is the cause and solution for SAP error message D7026 - &1: Aggregate fct. returned either more than one row or neg. # of rows ?

  The SAP error message D7026 indicates that an aggregate function in a query has returned either more than one row or a negative number of rows. This typically occurs in the context of ABAP programming or when working with database queries in SAP.
  Cause:
  
  
  Multiple Rows Returned: The aggregate function (like SUM, COUNT, AVG, etc.) is expected to return a single value, but the query is returning multiple rows. This can happen if the GROUP BY clause is not used correctly or if the selection criteria are too broad.
  
  
  Negative Number of Rows: This can occur if there is an issue with the data being processed, such as incorrect calculations or data inconsistencies.
  
  
  Solution:
  
  
  Check the Query: Review the SQL query or ABAP code that is generating the error. Ensure that the aggregate function is being used correctly and that the GROUP BY clause is applied appropriately to ensure that only one row is returned.
  
  
  Use DISTINCT: If applicable, consider using the DISTINCT keyword to ensure that duplicate rows are not causing the aggregate function to return multiple values.
  
  
  Debugging: Use debugging tools in SAP to step through the code and identify where the multiple rows are being generated. This can help pinpoint the exact cause of the issue.
  
  
  Data Validation: Check the underlying data for inconsistencies or errors that might lead to unexpected results. Ensure that the data being processed is valid and meets the expected criteria.
  
  
  Modify Logic: If the logic of the program or query is incorrect, modify it to ensure that it aligns with the intended functionality. This may involve changing how data is grouped or filtered.
