Hi @Rekha I
Good day! We can use the attribute launch script (Run Action) here. In the launch point, you need to select the WORKORDER Status attribute.
and based on the relation with the custom table, you need to fetch the MboSet(), and then in the if block, you have to check the work order status, and if it's changed or set to a business requirement, you have to use the custableMbo.setValue('Attributename','Value to be populated');
