field in warehouse setup

hi to everyone…

there is a field called " Last whse. posting ref no. " m not able to know at wat time this field is effected…can u explain me in detail about this field…reply wuld be appreciable…

I believe this is a running count of certain warehouse based transactions (picks and putaways). The warehouse ledger entry table holds this by entry number for each item, but this field treats one document as an entry. I have never really paid it any attention as it is not something you control, the record increments based upon postings and you cannot re-reference the information from this screen.
