Form Personalization to avoid duplicate PAN number to different vendors.
Hi,
Can anyone please tell how can we make a personalization for PAN number field in third party registration form so that :
- It has to allow same PAN number to a vendor with any number of sites.
- It should not allow the 2nd vendor to accept any PAN number that already a vendor has or assigned. He has to be given a new PAN number.
I tried to do this by writing a function in a package but it seems not to satisfy both the conditions.
I have tried a personalization too where it is also satisfying any one of the above said condition but not both.
