Vendor master - Tax Number 3 - Duplication check (GSTIN duplication check for India)

[VKK]

Dear experts,

While creating Vendor master in SAP, I need to check whether same value has already been entered in 'Tax Number 3' field [LFA1-STCD3] - (i.e. field used for GST Identification Number for vendors in India) for another vendor and prevent it.

I searched in SCN and followed all the steps mentioned in the below thread:

https://archive.sap.com/discussions/thread/1577212

As mentioned in the thread, I even created a new tax category and turned 'On' the duplication check in transaction BUPA_TAXNUMTYPE for India.

But I don't know how to use this tax category while creating vendor master.

I even noted that the option 'XK02 --> Extras --> Tax categories' is hidden.

Does this option has anything to do with this duplication check?

Or did I miss any other step required for duplication check?

Or any other better methods available to carry-out this duplication check?

Please guide me.

Thanks in advance.

Have a nice day 🙂

This is not applicable for tax number 3 field. You need to make your own enhancement to do this.

Dear Dibyendu Patra,

Thanks for your reply. Can you please throw me some light on why is it not possible for Tax number 3 field?

I have seen an SCN thread where the validation has been maintained for the field w.r.to Brazil country. Refer below,

Any other inputs from you please?

I am not aware of Brazil country scenario, hence can't explain about this. During GST implementation, we have faced the same scenario, but didn't find any solution in standard.

Dear Dibyendu Patra,

Thanks. Let me wait for inputs from other experts before going with custom validation 🙂
