Stock Receipting - override previous receipt

Hello,

I have an issue with partial Order stock receipts, where any new "Receive Items" will override the previous "receive items" to date, not only in the Purchase Order, but also in the Stock Card as well as the General Ledger for my G/L accounts:

Dr Stock

CR GRIR (goods received not invoiced) - for receipt of stock

For example, if I have an order of 10, but receipt 5 on 21/2/25, and then receipt the remaining 5 on the 1/3/25, the receipt transaction will completely override my stock receipt of 5 on the 21st Feb and make the full stock receipt of 10 on the 1/3/25. 

This does not work for a month end closure, whereby we are closing the books for the month for February, however the full receipt is now removed in February and put through March. Once the monthend book is locked, we CANNOT through system entries, be adjusting any entries.

What is the solution for this. As we have a warehouse who will be creating the Purchase Order and then clicking Receive Items once stock is received; the Accounts Payable will be the only ones to have access to the "BILL" function once the bill is received and can be entered with the attachment once approved, they are not changing the received items, but are only interested in what is the qty of the bill item to enter, that will match off against receipt.

 I need a workable solution please. Thanks so much.
