Issue in language determination for Standard text in smartforms

Hi,

I am using standard text for heading in smartforms for English and Swedish languages.

Below details are passed :-

TEXTKEY-OBJECT = 'TEXT'

TEXTKEY-NAME = 'Y_WS_INV_ITEMNO'

TEXTKEY-ID = 'ST'.

TEXTKEY-LANG = '&Y_LANG&'. [Y_LANG is populated as S for swedish (SV) language ]

Standard text is maintainde in SV language.

In production it is printing swedish invoice in original language (English) where as it works properly in Quality box.

On comparing I can find the only difference is in SAP standard global variable %LANGUAGES value is 'VE' in Quality and 'E' in Production.

Please help me to find root cause of this issue.

Thanks,

Rupali
