Item Allocation Issue for an Unposted PA Inv Transfer

Hi Folks

On GP 12.00.2084(R2) or 12.00.1745(R2) I have the same problem.   I have an unposted Project Accounting [PA] Inv Trf Entry and although the Item enquiry correctly states that it is Allocated, I cannot drill down to see the documents causing that allocation.    The Stock Status correctly reflects that it is allocated, but I need to be able to drill down onto it.  

This is a serious issue for me and I'm hoping that there is a solution out there.   Any assistance would be greatly appreciated.

Would you know if this is a bug?

Thanks
