Hello Amol,
you can influence the order of the displayed fields using the SET_AVAILABLE_FIELDS method of the IDA ALVs field catalog instance.
Following you see a little example for the company code table T001. I changed the order of the fields that the company code text is displayed in front of the company code ID. The order in which you pass the fields to the method defines the order for the output.
Best Regards,
Florian
