Hello vipra,
i will be more inflexible than Konstantin: you customer request has absolutely no sense 
All master data depending on languages must be maintained for used languages in SAP system !!
For example, if PO layout are sent to suppliers in their own language, unite of measure must have a commercial format...
If you do not want to maintain master data depending on languages, this means you must use only English language for example.
Regards.
Laurent.
