Purchase Receipt Accounting Issue


I need to understand that how accounting behind purchase receipt is working,
the problem is system calculating different values for warehouse’s account and expense’s account, and difference is going into stock received but not billed account,
i want to know why there is difference? each time, there is new value in difference.

In standard process, when you create a purchase receipt, your stock in hand/warehouse account will be debited and stock received bot billed will be credited. When you create purchase invoice stock record not billed will be debited and supplier will be credited. Please check your company settings. May be it’s some configuration issue. Which version you are using?

its v12,

stock received but not billed account is getting sometimes debit and sometimes credit,
supplier module raw material account is warehouse account, and prefroms is item’s row expense account.
