Hi Kanth,
First of all Sorry for delay of reply.
The fixed text in Arabic is no issue where you can change the language and type the fixed text in smartform/sapscript. but when you fetch data from database dynamically (eg employee name, designation) it would be display when you set the language of smartforms in FORM attributes options. But keep in mind database entries also maintained in Arabic language also.
More brief: if employee names are not maintained in Arabic language then it could not display employee name in smartforms. Mean user have to maintain these entries in Arabic language also.
Hope you understand the point.
regards,
Tayab Shah
