Could not find attribute LANGU
I have a webdynpro ABAP screen that is displaying the fields on infotype 0022.
But when I try to click on the dropdown for field SLART, I get the error "could not find attribute LANGU".
Within SAP GUI and accessing the infotype 0022 via PA20/PA30, the dropdown of course works fine. The Entry Help is trying to access check table T517T - Educational Establishment Type Designations, to display on the dropdown.
It appears that the webynpro app does not know what LANGU in order to perform the dropdown for SLART.
Anybody come across something like this?
