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 🙂

There are some OSS notes, which are country specific

There is a SAP note 1297182 - BP: TaxNumber: BUPA_TAX 400 is now customizied

and OSS note 707035 - Duplicity Check for Tax Numbers

In both SAP said that this check was not programmed at all or not for tax code 3.

It was actually delivered then with a service package. However, I found such notes only for Brazil country version.

You may want to check with SAP support if this available for your country version too, before you do your own validation.
