Use
It is still possible to post to Accounting if Accounting is in an R/3 system with a release status of 4.0A or above and Payroll is in an R/3 system with a release status below 4.0A or is in an R/2 system.
When posting to Accounting, only the functions available in both release statuses are supported. In the following, the most important functions and restrictions are named:
Prerequisites
Procedure
In order to post from HR systems with a release status lower than 4.0A, you must create a TemSe file, from which posting documents are created, after completing payroll in the Accounting system (AC-system). You have two options for creating this TemSe file:

If you want to use ALE technology for this purpose, you must make the relevant settings in ALE Customizing.
If the HR system has a release status lower than 3.1G, you can only post using a file transfer.
Posting Using a File Transfer
Steps in the HR System (Sending System)
The HR system evaluates the payroll results and writes the posting-relevant information to a TemSe file.
The HR system creates a second modified TemSe file from the first TemSe file.
The HR system creates a work file on the presentation or application server from the second TemSe file.
Steps in the AC System (Receiving System)
The AC system creates a TemSe file.
The AC system creates posting documents from the data for the TemSe file. These documents are grouped together in one posting run.
