Custom program to mass cancel workflow items

Mass cancellation of work items is possible with the SWIA transaction as explained in this blog.

This blog will explain how you can use Z program to mass close like SWIA, but then in batch job mode, and automatically without user interaction.

The custom program

The custom program ZRSWIWILS_WI_CANCEL is basically a copy of standard SAP program RSWIWILS.

You can copy and paste the code from below source code text and add the text symbols and selection screen parameter text.

Start screen has 1 extra option more than standard SAP:

The program working explained

When the new option is selected, after the data fetching, the program simply calls function module SWW_WI_ADMIN_CANCEL to cancel the item. Since it is done in loop and without user interaction, the program can run in batch mode.
