Smartform to display in Vendor Language[LFA1-SPRAS]

Hi,

I have a smartform in EN language , I have selected the radio button for all language on the global settings page

I have also created translations via SE63 to other language , but the user wants the smartform display not in logon language but the vendor language LFA1-SPRAS , Kindly note that SF is triggered from T-code MR91 hence I cannot control the language parameter . Please advice me some solution.

Thanks & Regards
