You would like to understand the value posted to the Stock Account (BSX) on Goods received for a Purchase Order when the stock was negative before posting.
First of all, let’s take into account the concept of negative stocks:
Negative stocks are allowed when the goods issue needs to be done urgently. Just due to organizational reasons goods issues are entered before the corresponding goods receipts.
Once the goods receipts have been posted, the book inventory balance must again correspond to the physical stock, that is, the book inventory balance may no longer be negative.
Negative stocks are always a sign that physical movements must be entered into the system at a later stage.
So that negative stocks are allowed, the 'Negative stocks' indicator should be marked into the material master data via MM01/MM02 transactions on the General Plant Data 2 view at the ‘General Plant Parameters’ screen.
You have also to allow negative stocks by Plant. Trx.: OMJ1
Example: Goods Receipt Valuation when allowing negative stocks
Imagine that you are notified you have negative stocks in MMBE transaction and a corresponding negative value in MM03.
For example, you have -10 kg valuated at -700 USD (Moving Average Price of 140 USD/kg)
It's created a Purchase Order in the ME21N transaction for 20 kg.
After that, it's posted a Goods Receipt for the Purchase Order in MIGO transaction for 20 kg.
Checked the stock position after posting the GR in the MMBE transaction.
Goods receipt was done by 20 kg. So we have -10 kg + 20 kg = 10 kg.
Calculating the GR value (WRX)
Data (for example):
PO qty = 20 kg
PO Net price: 150 USD
PO price unit: 1 kg
GR qty: 20 kg
Formulas:
PO Net Value = PO qty x (PO Net price / PO price unit)
GR value = GR qty x (PO net value / PO qty)
Calculation:
PO Net Value = PO qty x (PO Net price / PO price unit)
PO Net Value = 20 kg x (150 USD / 1 kg) = 1500 USD.
GR value = GR qty x (PO net value / PO qty)
GR value = 20 kg x (1500 USD / 20 kg) = 1500 USD.
Calculating the stock account value
Data (for example):
-10 kg valuated at -700 USD (Moving Average Price of 140 USD/kg)
Process:
The first 10 kg in the reception will clear the negative stock. After receiving the first 10 kg, the stock will be zero. Since the stock will be zero, the value needs to be cleared also. The first 10 kg are valuated at 700 USD in order to clear the stock value.
Then, the remaining 10 kg are valuated according to the value given externally by the purchase order:
10 kg x 1500 USD / 20kg = 750 USD.
The total value posted to stock is:
BSX = 700 USD + 750 USD = 1450 USD.
Calculating the price difference value
PRD = WRX - BSX
PRD = 1500 USD - 1450 USD = 50 USD.
Now Check the FI document via ME23N (PO history), MB03 (via material document) or in the FB03 directly.
With this example above you can see that the stock account would be debited on 1450 USD, the clearing account would be credited on 1500 USD and, as a consequence, the price difference account would be debited on 50 USD.
