Value set of DFF with separator

Hi all,

There is needed to make a value set for a DFF to maintain the numeric entry from user. This is successfully done.

We made a value set XX_Numeric with List Type 'LOV', Security Type 'No Security', Format Type 'Number', Max Size 10, Precision 2, & Validation Type None'.

Here we need feature of auto placing comma separator. E.g. in Invoice Workbench form, we enter 1234567.89 in 'Invoice Amount' field, on pressing tab to move to next field, system place comma separator automatically & displays the value as 1,234,567.89. 

Please guide.

Regards,

Abdul Rehman.
