Filtering content in the SRM confirmation worklist

Hi

I'm quite new to SRM and am having some trouble implementing BAdI BBP_WF_LIST. I'm hoping someone on SDN can just give me a nudge in the right direction...

I am trying to filter the content of the worklist a user sees in the transaction BBPCF03, Confirmation Goods/Services Centrally. Within the BAdI BBP_WF_LIST, I have set the object filter to BUS2203 to restrict the content filter to confirmations.

I have then written some code (see below) to get some information about the user, and I want to remove the confirmations where the purchasing organisation of the user does not match the purchasing organisation of the confirmation. However, when I debug the code, these fields within table i_pdlist are blank.

I guess I am missing something somewhere, but basically I need your help in getting the purchasing organisation for each item. Do I need to go and get the relevant purchase order for this? If anyone can point me in the right direction, you'd be a great help. I've pasted my code below so hopefully someone can see what I'm doing wrong!

Thanks again, from your SRM newbie, James.
