Hi Friends,

I have a basic question. What is the use of dynamic selections in LDB?

Thanks in advance.

Regards,

nathan.

Nathan,

SELECTION-SCREEN DYNAMIC SELECTIONS FOR NODE|TABLE <node>.

If the node <node> is requested by the user of the logical databases, the dynamic selections are included in the selection screen. A user can then choose Dynamic selections to enter extra selections for the corresponding fields. If you call the logical database using the function module LDB_PROCESS, you can pass a corresponding parameter. You can use these selections in dynamic statements in the logical database program to read data. The values of the program-specific selection criteria that you defined for a node for which dynamic selections were available are also passed to the logical database. The user can also define the fields for dynamic selections as a selection view for the logical database.

The selection screen of a logical database is part of the standard selection screen (number 1000) of the executable program to which the logical database is attached. It has a standardized layout - the selection criteria and parameters appear on separate lines in the order in which they were declared. You can change the layout using the SELECTION-SCREEN statement.

The runtime environment generates the selection screen with number 1000 for every program in which the attributes do not contain a different selection screen version. You can prevent certain input fields from the selection screen of a logical database from appearing on the selection screen by defining selection screen versions with a screen number lower than 1000 in the selection include, and entering this version number in the program attributes. By pressing F4 there, you can get an overview of the selection screen versions defined in the logical database concerned. To define a selection screen version, use the statements SELECTION-SCREEN BEGIN|END OF VERSION. Within these statements you can use SELECTION-SCREEN EXCLUDE to specify fields that you do not want to appear on the selection screen.

If the attributes of an executable program contain the number of a selection screen version, the version is used in the standard selection screen. Although the input fields that you excluded from the selection screen are not displayed, the corresponding selections still exist, and you can still edit them in the program or by calling the function module LDB_PROCESS.

Pls. Mark if useful

in every ldb there is a selection screen defined so when you use that ldb that pre defined selection screen will come automatically and you can fetch the value for that selection criteria. But in some cases that selection screen doesnot fulfill your requirement so most of the ldb contains dynamic selection i.e they are not appearing in default selection screen but if you click on dynamic selection button then it will show some other fields which you can incorporate in selection screen.

dynamic selection button you can see in application tool bar selection screen after the execute button. If you click that a list of other fields will appear at the runtime only you are defining the selection criteria so it is called dynamic selection .

Hi,

Dynamic selections: as the name tell you, it is to change the selection screen dynamically.

You can select which fields you want to be included in your select criteria.

Based on your selection the options will be created on the screen for you to enter values.
