How to create a Domain in SAP ABAP

Domains 
A domain defines a value range. A domain is assigned to a data element. All table fields or structure components that use this data element then have the value range defined by the domain. The relationship between the field or component and the domain is thus defined by the data element of the field or component.
Fields or components that refer to the same domain (with the assigned data elements) are also changed when the domain is changed. This ensures that the value ranges of these fields or components are consistent. Fields or components that are technically the same can thus be combined with a reference to the same domain.

The value range of a domain can be restricted by defining fixed values. If all the fields or components that refer to the domain should be checked against a certain table, this table can be defined as the value table of the domain.
Output attributes can also be defined for all the fields or components that refer to the domain (see Creating Domains). A conversion routine can be assigned to a domain. This conversion routine converts values from display format to internal format for the fields or components that refer to this domain.

How to create Interactive Report in SAP ABAP

Image
Interactive Reports As the name suggests, the user can Interact with the report. We can have a drill down into the report data. For example, Column one of the report displays the material numbers, and the user feels that he needs some more specific data about the vendor for that material, he can HIDE that data under those material numbers. And when the user clicks the material number, another report (actually sub report/secondary list) which displays the vendor details will be displayed. We can have a basic list (number starts from 0) and 20 secondary lists (1 to 21). Events associated with Interactive Reports are: AT LINE-SELECTION AT USER-COMMAND AT PF<key> TOP-OF-PAGE DURING LINE-SELECTION. HIDE statement holds the data to be displayed in the secondary list. sy-lisel : contains data of the selected line. sy-lsind : contains the level of report (from 0 to 21) Interactive Report Events: AT LINE-SELECTION : This Event triggers when we double click a line on the list
