Unable to close wip peiods using perpatual costing

[zeshan.acca]

Hi all

we are unable to close wip periods using perpatual costing, the problem is that at period end wip completeion should be equal to wip issues with value. But it gives diffrence always in value. How we can adjust these diffrences when we have no more quantities to complete.

Furhermore can we close job before the date of any transaction e.g wip completion in 05-jun09 & job close in 01jun09. Is there any nevigatio, function??

Regards
