Generally this problem occurs when the inventory is update physically but not financially.
I got the same problem - let us take the example of production process - the picking list will posted due to the availability of physical stock - and when trying to End the production the system will through this kind of error.(Means some of the transactions of the raw materials used in the production process are not financially updated (or) use negative financial inventory to avoid it.
To certain extent your point is correct. Actually it needs Financial Negative Inventory ticked in Inventory Model group or Item as a service item. But I don’t know why. Because splitting of fixed assets post following two entries
First Entry
Fixed Assets------Dr
Inventory Issue
2nd Entry
Fixed Asstets -----Dr
Fixed Assets
I need to know why it is posting First Entry. Because it is not required entry at all. Is it a bug?? or there is Set Up problem in our side?? Or there is a functional Logic???
