Annexure 5: How to Translate Labels in CDS Views

Column labels, Field Labels, Report names etc. can be specified while creating CDS Views. The Column and Fields can pick up labels from their corresponding Data Elements. This ensures that the translations for the Data Element Labels are available to the fields and thus no separate Translation needs to be done.

However, it is also possible to add fields in field list as literals that do not refer to any Data Element in particular. In such cases the field labels can still be specified using the Annotation “@EndUserText.label:”

The same annotation can also be used to specify the report name that is visible to the end user while consuming the report via an analytical client.  So how does one translate the labels that have been specified by using @EndUserText.Label: ?

Similar to other DDIC objects CDS Views are also translatable via TCODE SE63 (Translation Editor). 

• Go to Transaction SE63 and client Button “Short Texts”.

• On the Object type Selection Box Double click on A5 User Interface Texts -> DDLS CDS Views. Alternatively use the search buttons to find DDLS and then double click on it to move to next screen.

• Give CDS name and Enter Source and Target Language and then Press “Edit”

• Subsequent screen opens with labels in Original Language and blank fields where corresponding translations can be given in target language. Save the changes when done
