Account assignment data is missing in PO created from SRM

Dear All,

We have SRM7 (Upgraded from SRM 3), having some problems. In one cycle, from Shopping Cart to Auction and then from that Auction if we create PO, there the account assignment data are not populating which was there in Shopping Cart. However those account assignment data are present when we are creating PO from RFx response ,

I am not sure whether this is standard behavior or not, if yes then some explanation if you can provide. But if it is not the standard behavior then which part i am missing out. Please help us out.

Regards

PSB
