SAP Transactions

The backbone of SAP is at the transaction level.

An SAP transaction is any logical process in the SAP system.

A SAP logical unit of work (LUW) contains all the necessary steps of a transaction. It concludes with the update to the SAP database, if necessary.

Lets say you are adding a new employee in the SAP ECC Human Resources module.

In order to complete this process you are required to go through various screens in SAP system.

You will be entering the employee's name and address on one screen.

You will then proceeding to the next screen.

The next screen is considered a dialog step within the process.

In this next screen you will add new employee's salary and paycheck information.

After you have gone through all the necessary screens in the process, the data is committed to the SAP database. This completes your LUW.

Each screen that you used was part of LUW. Until all the required information in not entered using all necessary screen, a logical unit of work (LUW) will not be completed.
