BADI for MDGF rule based workflow

Question

Hi Experts,
I am really struggling to get a badi that can route on field assigned in my single and agent decision tables. I have used the standard BADI that was provided in RDS documentation for BP and Materials and just tried to change the entity name and field names without success.
Can anyone please provide me with an example where someone has used this to route on field in finance.
I am trying to route on Segment for Profit center
Your help will be highly appreciated
Thanks and best regards

Hi Abdullah,
I am using an existing attribute in the data model OG in the entity PCTR. The field name is PCTRSEG and element is fb_segment. In my rule based workflow in the Single decision table I have added fb_segment and I have populated the values against step 00. I have also updated my agent decision table with the fb_segment value.
I am attaching the BADI that I am struggeling with.
The service name for the change request is in the BADI filter. Thus when the requestor submit the Badi will be called and it will route to the person assigned in my agent decision table against the relevant segment..
My problem is the following:
The issue is that I don't know where I should maintain PCTRSEG and where I should maintain fb_segment in the BADI. Thus, where do I use the attribute name from the data model and where do I use the data element from the model.
When the requestor submit the request it does not go to the next approver and I get the error" Agent could not be determined"
I found ,when I change any of the values for the segment in the single and agent decision tables to not equal, example <> 1001 that the workflow works but all change requests will go to the same person.
Thus my assumption is that something might be wrong with the BADI
Your help will be highly appreciated
Thanks
