Reduce number of columns of a result set from a Transaction in SAP system

The simple answer to your question is NO. This is SAP standard behavior, and if you want to restrict the number of columns to be returned, it will require you to change the original source code of SAP implementation.

Why Column Reduction is Not Recommended

The change will be quite exhaustive and it will also mean that you are violating the contract and hence, no support from SAP on any issue encountered later. Modifying SAP's core transaction logic breaks the standard functionality and voids official support agreements.

Performance Considerations

As you mentioned, you are filtering data, which means the number of rows will not be huge and hence the number of columns will not have much implication on the performance of the transaction overall at a high level. SAP transactions are optimized to handle standard column sets efficiently.

Alternative Solutions

If you do want to have the flexibility that you require, please opt for other approaches like SAP Query. SAP Query allows you to create custom reports with specific column selections without modifying core SAP code.

SAP Query Example Structure

Here's how you can structure a basic SAP Query to select specific columns ?

* SAP Query example for custom column selection
* Navigate to: SAP Menu > Tools > ABAP Workbench > Utilities > SAP Query
* Select desired fields from available tables
* Define output format with required columns only

SELECT field1, field2, field3
FROM table_name
WHERE conditions
INTO CORRESPONDING FIELDS OF internal_table.

Other alternatives include creating custom reports using ABAP development or utilizing SAP Business Intelligence tools for data extraction with column customization.

Conclusion

While reducing columns in SAP transaction result sets is technically not feasible without code modification, SAP Query and custom reporting solutions provide viable alternatives for achieving column-specific data extraction while maintaining system integrity and support compliance.
