DATA ELEMENTS

We cannot use Domain directly neither in a Report/Program nor as a table field. We need to add some semantic information i.e. Field Label, heading, etc. For this purpose we need data elements.

Definition:

Data Elements are reusable objects that are used to add Field Label, Heading, Documentation (F1 Help) and assign a parameter ID and a Search Help (F4 Help).

Note:  In Domain Level also we have an option to define Search Help which fetches either fixed value defined there or from Value Help Table while the one we assign in Data Element is from Global Search Helps that we create via SE11.

Creation of Data Elements:

#Using ABAP Dictionary

Step 01: Open SE11.

Step 02: Click Data type Radio Button and give your Data Element name starting with Z or Y e.g. “ZBarry_DataElement”.

Step 03: Click Create, Choose Data Element Radio Button and Enter explanatory description for Data Element in Short Description e.g. “Data Element for Test”. This short Text appears as title of Data Element F1 help Documentation.

Step 04: Under Data Type Tab, you will have two options.  Choose any one and provide its corresponding details.
