Investigate one of the development tools in SAP – Runtime analysis

Review data in the SAP R/3 Repository

Use the ABAP Development Workbench

The Help System

The HELP system included with SAP is extremely detailed – in addition to providing information to the user on how to run the system, it also provides technical information for the developer or programmer You will now examine some of the features of this extended Help

1 Type /nSU3 in the Command Field on the Standard Toolbar

The Maintain User Profile Screen will be displayed

5 Close the Help windows then click or to return to the SAP standard menu

Customised User Menus

End users in SAP will typically only use a small number of screens as part of their daily job routine (10 – 20 screens) Instead of navigating through the standard menus each time, it may

be easier to set up a customised menu for each user, containing only the transactions he or she needs (or is allowed to use)

6 From the Menu Bar choose Favorites => Insert Folder

7 Enter the file name “Manufacturing Menu” and press <ENTER>

The new folder will be added to your “Favorites” menu

8 Select the new folder and then choose Favorites => Insert Transaction

9 Enter transaction code MM01 and press <ENTER>

The “Create Material” transaction will be added to your menu

10 In the same way add the following transaction codes to the Manufacturing Menu:

ME22 Change Purchase Order

CR03 Display Work Centre

MB1A Goods Withdrawal

MK01 Create Vendor

Your Favorites menu should now look like:

If the sequence of transactions is different to that shown, you can rearrange them using the 

and buttons on the Applications Tool Bar Try it !

11 Now create another folder on the same level as the Manufacturing Menu Call this folder

“Accounting Menu”

12 You can also add transactions to your Favorites menu by “dragging” them from the SAP

standard menu Navigate through the standard menu as follows:

Accounting => Financial Accounting => General Ledger => Master Records => G/L Accounts => Individual Processing => in Chart of Accounts

Drag this transaction onto your Accounting Menu folder

13 Add another two or three Accounting Transactions to your Favorites menu until it looks

something like this (you can use any transactions):

14 Test out each of the options on your new menu

Defining Default Values

If a user always enters the same value in a particular field on a screen, it may be possible to save time by defining a default value for that field In this way the field will always have that value when the screen is initially displayed
