Hi Sudhir J :
When I am looking for Workflow standards, that's what I do:
Maybe is not the easiest solution but it work's for me
1.- Go to the transaction <b>SWETYPV</b>.
In that transaction you can see all the buses and workflow that the system has.
Is the relation between the bus and WF.
You have to make a list of all the buses that you have there.
2.- in the transaction <b>SWO1</b> you can check for what is each bus and then you can choose which WF is going to work.
3.- In the transaction <b>SWDD</b> is the transaction for building WF you can enter the standard WF and look how is build. I recommend that if you are going to make some changes make a copy of the WF and work in the copy.
If you have any question, you can ask.
Best Regards
Jessica
