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

Nov 29, 2017 at 10:45 AM | 2.9k Views

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.

    I think, you need to change the message from W to E in OBA5

      Dear Lakshmipathi,

      Thanks for your reply. I have maintained it as 'E' only in OBA5.

      I think the problem exists in the place where we need to to use this tax new category (created for India) while creating vendor master. I don't know how to do it.

      Any other inputs from you please?

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