Workflow for Tran - ABUMN & ABAVN.

Hello,

I need to create 2 workflows for Asset Accounting.

1. Tran - ABUMN - Transfer within Company Code.

2. Tran - ABAVN - Asset Retirement by Scrapping

SAP has business object BUS1022 - Fixed Assets. However, there are no events for Asset Retirement or Asset Transfer. I can always extend this business object & add those 2 events and I can raise these events using SWE_EVENT_CREATE or similar FMs.

My question is -

1. Are you aware of any user exit/BADI, that I can use just before SAVE, where I can trigger these workflows?

2. Is there any other option available if the above cannot be used to trigger the workflow besides writing a custom transaction?

Appreciate your answers asap!

Thanks,

Rishi
