Hi Julien Patureau , therefore you previous example, is opposite to the afirmation? (maybe is my english)

"See before misc. receipt:

Both Last receipt cost and Last purchase price remain identical after the misc. receipt created at a different order price:

"

About the standard cost, i can not understand "Indeed, if you are using standard cost, following your proposition, the system should fed the above costs with the value matching the standard cost."

ast price, Average cost, Lot Average cost and FIFO are always calculated in Sage X3 disregarding the valuation method setup (based on VARORD and not VARVAL). Indeed, if you are using standard cost, following your proposition, the system should fed the above costs with the value matching the standard cost.

Hi Jonathan.gonzalez 
Indeed my initial test was showing no change after the misc. receipt, there is an inconsistency and I have reported the question to the support. But the on-line is very clear: misc. receipt should update the last receipt cost (based on the order price).
So this will not help you here.

You are expecting the last cost to remain identical after a misc. receipt because the valuation method is set with last cost. This is not the product logic, we are not using the valuation amount (VARVAL) but the order price (VARORD) to update the last cost (and other costs such as AVC). 
I tried to explain why using the valuation amount (VARVAL) is not a good idea to update the last cost by setting an example with standard cost. If you use standard cost to value your misc. receipt (VARVAL = standard cost), then the last cost would be, accordingly to your suggested logic, equal to the standard cost.  This will forbid any possible stock valuation simulation / comparison between last cost and standard cost. Moreover, if you decide to transition to a valuation method using standard cost to last cost, the initial value would be incorrect.

I hope I am clearer in this new post.

Thanks Julien for the new post.

We will try the development in misc receips and adjust the order price.
