Posting Date, and its impact on FI

Hi every one,

I want to ask about “posting date” and its impact on financial accounts with perpetual inventory.

Let me assume that I have a Purchase order for 100 pieces of material A with price 1$ for each piece.

And I have quantity=0 for this material.

After that I entered 3 documents:

  1- GR PO for 100 pieces.

  2- GI for 100 pieces.

  3- Invoice for 100 pieces @2$.

Because of insufficient coverage when the invoice was entered (quantity=0), 100$ would be debited to Expense account.

After these 3 documents general ledger would be like this:

Question is:

If I entered the 3 documents with the same order but with different “posting date” like this:

  1- GR PO for 100 pieces ,posting date= 1-1-2016.

  2- GI for 100 pieces ,posting date= 3-1-2016.

  3- Invoice for 100 pieces @2$ ,posting date= 2-1-2016.

Would this change the values posted to general ledger?

I mean: does system calculate the coverage quantity on “posting date”, or at the moment I enter the data to the system?

Thank you in advance,

Ismaiel.
