Any possibilty there to input only the negative amt. in input of a wagetype

HI Experts,

We got a specific requirement that we need to restrict for only negative amounts for a specific wagetype.

Is there any possibity to have this type of wagetype.

System has to accept only negative amounts in the wagetype amount field.It has to restict the positive amounts.

Please share your idea on this specific requirement.

Thanks in advance.

Regards,

Sairam.
