ReceiptAdvice Help Needed

Title: ReceiptAdvice Help Needed

Hello, I am new to this list and need some help.  I am trying to use the ReceiptAdvice
much as one would use the 944 in X12 EDI (that is the Warehouse Stock Transfer Receipt Advice).  Actually the information that we need is not too complex and this document seems to work well enough, save for a few items which I would like to ask about.

We send a Despatch Advice and want to get the ReceiptAdvice back once the goods have  arrived at the warehouse. 

I am curious about where I could put the following:

1) Invoice Number.  We need this back in the ReceiptAdvice, so I need to know an appropriate element that I could use.  I researched this but I dont find an appropriate element in the ReceiptAdvice. Please help me out.

2) <BUYERParty> and <SellerParty> do not exactly describe the relationship between
us (an OEM) and the warehouse.  Is there somewhere else I could put this information?

Sorry if my questions are naive. I am usually a developer but have now found myself additionally taking on a role of business analyst, and I am quite new to UBL.

Thanks,
