What is "POSNR" an abreviation or acronym for?

Question

I'm working with some data that's coming out of an SAP system. There's a field named

POSNR

that appears to be a line item/database identifier of some kind. What is this an abbreviation for? It's not hyper-critical to what I'm doing, but every time I stare at the word it looks like pure gibberish and can be slightly distracting.

Answer 1

I'm not an SAP expert but could it be "Item number of sales document"?
