Consider the following scenario:

I have posted a purchase receipt and purchase invoice for an item, on posting date 11 April 2022.

On the same day, I have posted a sales shipment and sales invoice for these items.

A few weeks later, on 2 May 2022, I post a purchase invoice for the transport (item charge) and assign it to the purchase receipt. This also affects the sales shipment.

My issue now is with the inventory value on the different posting dates: the revaluation of the inventory value is posted on 2 separate days:

- On the (later) posting date of the item charge invoice for the purchase entry - 2 May 2022

- On the (earlier) posting date of the sales shipment for the sales entry - 11 April 2022

This now means that on 11 April 2022 I have a negative inventory value!

From a financial/fiscal point of view, this is not correct.

The issue can -sort of - be avoided by using inventory periods, but shouldn't the posting dates be the same?
