PO Release with ACC "A"

Hi,

We have configured the PO Released based on Netorder Value and Purchase org. We have created Two characters for NETVALUE because we need to USD and GBP value. Basd on the link which given by Jurgen setted this and working perfectly.

Created 3 Strategies R1 ( BM release) R2 for (BM and RM Release) . for UK R3 (BM and DM release for UK)

If i add ACC as Character then these Release strategy won't change there strategy, these will release based on Value and Pur Org only

Now Requirement if Accoount assigned PR converted in to PO with ACC"A" (ASSET PO) for US, Then this PO should release only One Appproval i,e VP

if Accoount assigned PR converted in to PO with ACC"A" (ASSET PO) for UK, Then this PO should release only One Appproval i,e CFO.

As we all know that CEKKO doesnot have KNTTP fields and Item level release also not possible, How to achive this If i append the KNTTP in CEKKO strucure is it works or Shall i go through User Exit , if yes , what may be the logic, If go through User exit , is there necessary to create Chracter if which field we use? or shall we control through Logic only? How to proceed!

Thanks
