There is a function to calculate the cost without negative inventoy items?

Do you know, what is the function of this profile GMF:Exclude Negative Inventory Balance  on YES value?

With this fuction, Is the system capable to exclude the negative values and only calculate the cost whit the positive inventory movements? or there is another function to do it?

We do the following test:

If the profile "GMF:Exclude Negative Inventory Balance" has a "YES" value, and then  we run the process  :

. Actual Cost Process

. Cost Update Process  with the flag Final update

Then we check the result:

There is identified an item, that by the end of the month had a negative inventory (September), and after the process the cost goes over any cost (any value) to a zero cost in the current period (October).
