Accounting periods problem

[Wahur]

Dear friends!
I guess I must be explaining something in a completely wrong way, cause your
answers completely miss the point of my question. Maybe its my language - I
am not a native English-speaker. So I am very sorry for confusion.
I do use accrual accounting, for sure, so payment date is completely
irrelevant to my question. Having a degree in finance I also have no problem
figuring out transactions I need. All the accounts have been set up just
fine and they have been used successfully for a year.

Lets try once more.
Bill should be identified by two data items - here in Estonia we use usually
'Issue date' and number (number alone is not enough cause documents from
different issuers might match). Using Issue date is also convenient in case
i need to compare paper trail with electronic record - I can just look at
the bill and find it by the issue date.
So I need to record it somehow.
When I enter a bill in Gnucash, I post it to 'Issue date'. Right or wrong,
but currently it seems to me its the only way.
When I do that, many of my bills get accounted in a wrong month, because
they are issued during the next month.

So my question is - if there is a way in gnucash to record a bill so it
appears on a correct issue date AND still have it accounted in a correct
accounting period.
