purchase order worklist - Hide REJECT columne in ALV Report

Hi Experts,

I'm facing an issue with Purchase Order Worklist in Supplier Network Collaboration(SNC) system. Please have brief about the following screen-shot with yellow marked Reject column.

Business requirement is - Users expected that hide the REJECT Column in the Process Due Confirmations. Please check below round marked column. I have found the feeder classes and implemented enhancement but not reflected the ALV report.

Is other alternative to hide the REJECT Column for all the users.

Looking forward your best inputs to overcome this requirement.

Thank You,

Best Regards

Venkatesh
