Even though you have a fully settled receipt transaction, what happens if you want to adjust a purchase price on a fully settled receipt transaction. What happens if it is linked to a fully settled issue transaction.
In my mind, being fully or partially settled is not relevant for the question we are considering. If you adjust a receipt of inventory, it passes those adjustments on to issues of inventory. I think fully settled transactions become relevant when the close/recalc algorithm is setting up new links - any fully settled transactions would not be considered according to a flag. I am thinking of FIFO mainly as I think of this because it is simple, but the rationale can be extended to WEIGHTED AVERAGE as well. George
