Workflow for Vendor Creation through a portal.

Question

Hi All Workflow Experts,
                                     I have a scenario here.In my project  vendor is created through a portal.On submit button from portal the workflow is to be triggered.I have to design the workflow process.So can you please guide me through what all should i consider while i design this workflow?
This is my first workflow assignment so if you explain in detail it will be a great help.
I will just pen down what all scenarios i can think of:
1.Start workflow after vendor creation or modification.
2.Check whether approver are maintained in Org structure through  standard FMu2019s.
3.Check If approvers are maintained ?
4.If yes,approve or reject the vendor.
5.If no,get the agents from the custom table who can take an action on this.
This is what i can think of.
Please guide me.
Thanks in Advance,
Saket.

Answer 1

The corresponding BO related with the vendor creation or changing is LFA1 but this Business object doeanot have any events that are related to Create and Change , so try to create a ZLFA1 and add you own events or make use of delegation concept where you will create a delegation for LFA1.
For your first isssue
Start workflow after vendor creation or modification
EXIT_SAPMF02K_001 Vendors: User Exit for Checks prior to Saving is the user exit where in you can call the workflow when ever you change or create , because this user exit will trigger when ever you try to save the vendor. so i think you can make use of this user exit
For your second Issue
Check whether approver are maintained in Org structure through standard FMu2019s.
Make use of SWI_GET_USERS_OF_ORG_UNIT this fucntion mdoule to get the user of the ORG unit
or you can create a Rule(for determining the agents dynamically) to find the approvers.
