" The functions Hold data and Set data is used when you want to create a group of objects that contain the same data. The function Hold data can be used to create data that can be changed, for example if you wish to create multiple objects with slight variation in the field values (Sales order or Purchase order) then the function Hold data can be used. If you wish to create multiple objects with exactly the same data without changing any of the filed values then SET data can be used. To hold data on the screen you need to first enter the data in the field and then choose User Profile from the Systems Menu. Now choose Hold data. The data that you hold on the screen can be changed. In case if you wish to hold data on the screen without changing it then select SET data. This way the data will be held but you will not be able to change the contents of the individual fields. You can delete the Data that is held. To do this select User profile from the Systems menu and select the option Delete data. Once the delete Data option is selected no data will be displayed the next time you visit the screen. You may want to work in more than one screen, and would like to store data in each screen, to do this you can press Ctrl+S or click on the save icon while moving between screens. You can also Cancel the data that you have just entered on the screen. To do this press the cancel button. Please note that when using HOLD data and SET data options, the required/Mandatory fields on the screen cannot be ignored. The correct values should be entered in these fields before proceeding to the next screen. Using the menus and functions you can go to the other screens within your task, as well as in related tasks. Check the Goto Extras and Environment menus in the Menu bar to find out the other screens available within your task and related tasks. Depending upon the task the contents also change. "
"The SAP Control Framework is used for the communication between the controls on the presentation server and the ABAP application server. In ABAP Objects, it is programmed, and contains a set of global classes that you can find in the Class Browser under Basis -> Frontend Services. Between the application server and presentation server these classes encapsulate the communication, which is implemented using Remote Function Calls. There is a global class, which encapsulates all application controls. In the class Browser under Basis -> Frontend Services or Basis -> Components Integration, you can find the SAP Basis Controls."
SAP has provided ways to make modifications to the standard functionality. This is termed as Enhancements. With the help of this An ABAPer can make changes to the standard SAP programs with the help of guidelines given by SAP. Pleas note that it is not advisable to make changes to SAP standard programs directly. The changes can be made in the form of enhancements using the User Exits given by SAP. One of the methods to identify the user exits for Sales and distribution is through IMG. We would be exploring other methods later in this month.
Enter transaction SPRO as shown below.
Click on SAP Reference IMG or press F5 as shown below
Select the Sales And Distribution option as shown in the figure below.
Select User Exits in Sales Document Processing as shown below
You should get a listing of all the user exits related to Sales Documents as shown below
Always specify your conditions in the Where-clause instead of checking
them yourself with check statements. The database system can then use an index
(if possible) and the network load is considerably less.
Always use Pretty Printer and Extended Program Check before releasing the code.
Do not leave unused code in the program. Comment the code thoroughly. Align the comments and the Code. Follow the SAP Standards and SAP Best Practices guidelines. It’s a good practice to take a dump of the code on your local drive.
