Get FIFO unit cost for a specific amount of specific items you are planning to subtract from inventory.
API inspects all the batches that are currently in stock, calculates (according to FIFO rules) how many items should be discounted from which batch (starting with the oldest ones), and returns the weighted average cost of the resulting lot.
This API call is useful when you plan to make an inventory transaction (eg. a sale, transfer or inventory writeoff), but want to know the exact total cost of the items before actually making the transaction.
You need to specify amount, because each batch may have a different cost. The amount that you require may have to be pulled from one or multiple batches, depending on how many items are left in each batch.
Please contact Erply support if you plan to use this API call. Your account may need updates or customizations to be applied.
