Hi AX Community
Our company is using the FIFO stock model with "Fixed receipt price" and allow Negative Physical stock. We recently ran a stock close and don't understand the settlement of a posted count journal.
Example:
The item has the following Cost prices activated:
R223.38 Activation Date: 2018-10-01 Activated on 2018-10-01
R200.71 Activation Date: 2018-08-13 Activated on 2018-08-13
On 2018-09-30 we posted a counting journal and it costed it at R200.71 which is the active cost for September.

What we don't understand is the settlement which took place when we executed the stock close for September.

The cost of the Counting Journal (Receipt transaction) was adjusted to the active price of October resulting in all the issued transactions for September (settled against this transaction) to be adjusted to the October cost of R233.38

All issue settlement show the Settlement Principle as FIFO
The receipt settlement for the counting journal is "Adjustment" with the Settlement type being "Complete adjustment"

Does anyone know why AX would have adjusted it this way?
Please let me know if you require any further information.
