Hello,
When I use the session Standard Cost update, I get the next error message:
** unprocessed /unposted cost update transaction exists. Please process them first.

But where can post this transaction? When I go to the session "Unposted Documents" there is nothing to post

I have also the next problem:
Cost price prodcut "'X" : EUR 0,50
purchase 1000 product X for EUR 0,50 = EUR 500,00

Cost price prodcut "'X" : EUR 0,75
purchase 1000 product X for EUR 0,75 = EUR 750,00

Inventory/Product Asset value is now: EUR 500,00 + EUR 750,00 = EUR 1.250,00

NOW !!!!!!! When I sell 2000 products , the system wil calculate COGS with value EUR 1.500,00
booking
Prodct COGS EUR 1.500,00 debet
a/ Product Asset EUR 1.500,- credit

So now my Inventory/Product Asset is Negative :
EUR 500,00 + EUR 750,00 -/- EUR 1.500,00 = -/- EUR 250,00

NORMALLY when I change the cost price from EUR 0,50 to EUR 0,75 AND I update the inventory
it should revalue the inventory with 5000 products * EUR 0,25 = EUR 250,00

SO the question is NOW HOW can the system update the inventory when I change the current cost price????

With kind regards,
