Sometimes it is needed get the fixed values and texts of a domain into a report. The fixed values and texts can be selectes using the database view DD07V, but maybe the values are not maintained in logon language so that the developer has to check take care of having valid values. To make the work easier it’s possible to use CL_ABAP_ELEMDESCR. If no data is found for logon language or selected language the second language of the system is used.
Here you can find small sample report:
