Setting up the GST Identification Number (GSTIN)

The Goods and Services Taxpayer Identification Number (GSTIN) is a PAN-based registration number of 15 characters that is obtained from the tax authorities for each business unit in a state. The GSTIN does not exist in the standard address book, customer, or supplier records. You must specify the GSTIN for customers, suppliers, and GST units to calculate and process GST for your business transactions.

You use the Work With Address Book Additional Information form to enter the required GSTIN. You access this form from the Regional Info menu on the Address Book Revisions program (P01012). The system displays this form only if you have set the GST Applicable processing option for the PO - A/B Additional Info - IND program (P75I1012) to apply GST.

You also use the processing options for the PO - A/B Additional Info - IND program to set up the search type for suppliers, customers, and GST units. The system enables you to enter the GSTIN for the customer, supplier, and GST unit records that are set up with the search type that you specify in the processing options. If you do not specify the search types, the system allows you to enter the GSTIN for customers, suppliers, and GST units that are set up with the default search types of C, V, and GTU, respectively. If you select an address book record with an address search type other than customer, supplier, or GST unit, the system displays a message that user preference has not been set and does not display the Work With Address Book Additional Information form.

The system saves the GSTIN that you entered in the Localizations Additional Fields AB - 01 table (F7001100). The system validates the GSTIN that you entered when you perform the matching process to claim input tax credit.
