SAP

Dates meaning in SAP
Document Date
the date in which the business transaction for the Document
(e.g., a transfer of posting or the issue date of an invoice or payment) took place.


Entry Date
the date the transaction was actually "permanently entered" into R/3.

Posting Date
Posting Date determines the posting period and defines in which fiscal period a document will post (regardless of the Document or Entry date).

The periods that are permitted for posting are determined by Accounting Services.

This is the date that G/L Account Balances are updated.
The Posting Date will override the Fiscal Period entered on a document if they are different.

value date is the check date

baseline date is the due date


Note:
It is possible that an invoice was issued with a
Document Date of 6/15/98,
entered into R/3 on 7/15/98 (Entry Date)
with a Posting Date of 6/30/98
(to post the Document in the previous fiscal year).

Many times, all three of these dates are the same.
