Purchase Order corrections

goa

Hi folks,

I'v got a trouble \:D/ : need to fix posted Purchase Order (wrong dates, costs) when Sales Orders are already posted.

Was trying to rollback all the chain - Sales return, Purchase return, both with applying -, but something wrong with ma average (looks like some of returns affects (or not affects?) the average when posting new purchase).

NAV 403, average, Check Application Date, Exact Cost Reversing, no Allow Negative Stock...

Is there a some rule for such adjustments? Maybe ya should return ma sales using 'Inventory zero' param?

Thank you, thank you very much in advance!
