" 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. "
"A subset of Standard SQL that is fully integrated in ABAP is Open SQL statements. Their role is to help you by giving permission to access data irrespective of the database system, which the R/3 installation is using. The Data Manipulation Language (DML) part of the Standard SQL is present in the Open SQL. In other words, it gives you the permission to read (SELECT) and change (INSERT, UPDATE, DELETE) data. In the R/3 system, the tasks of the Data Definition Language (DDL) and Data Control Language (DCL) parts of the Standard SQL are performed by the ABAP dictionary and the authorization system."
Finding and Running programs in SAP is a fairly simple process. Every one know the transaction code SE38 The ABAP Editor. If you have forgotten the program name but you know that it starts with ZSales then you can type the ZSALES* in the transaction SE38 Program Input field and press F4 or the drop down button. You will then be presented with all the programs that have 'ZSALES' as the first 6 characters in their name.
You can also use the Transaction SA38 ABAP EXECUTE PROGRAMS to run programs. Mainly this transaction is used by the Users who do not want to edit/modify or create a new program.
Transaction SA38 does have options to execute the program with variant and in the back ground mode.
In case you wish to find a program either because you have forgotten the name or you are just looking for a report existing in the system, then you can use any of the Transactions mentioned above. Transaction SE38 has more flexibility.
Let us examine Transaction SE38 for the different options available for finding a program.
Transaction SE38 THE ABAP EDITOR
To find a Program in SAP ABAP goto Utilities >>>>> Find Program(CTRL+SHIFT+F4)
Once you are there you can either enter the Program name or Short Description or development class. All the programs with the same description and development class would be displayed depending on what you had entered.
Finding ABAP Program names based on the following criterion.
Program Author Last Changed By Changed On Program Type Status Application Logical Database Authorization Group Only Editor Lock Active Fixed Point Arithmetic Only
This can be easily achieved by clicking the 'ALL SELECTIONS ' Button (SHIFT+F7)
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.
