Purchase Order Layout selection....

Hi Gurus,

I need to choose the Purchase Order Layout based on the country(Country Specific Format) when print the Purchase Order.

Meaning, if it is India PO,then should go for Format A,

If it is US PO,then i should go for Formay B,

If it is Singapore,then i should go for Format C.

How to do the config for the same?.

Thanks in advance.

Thanks & Regards

Kavitha
