The invoice is posted automatically in ERS, therefore it’s impossible to capture the GST invoice number, this is utilized in GST returns.

During MIRO, is there a manual way of deriving tax conditions specifically for any exceptions such as in FI bills, HSN code different, Creditable or in the Non-creditable items.

Will GST taxes and Place of Supply (PoS) be consequent from the Bill to region?

Yes, as per our understanding of the section 10(1)(a) and 10(1)(b), of the model GST law, the Bill to Party regulates the place of supply and hence the GST taxes.

Section 10(1)(a) states that the POS shall be the place where the good terminates its movement for delivery to the recipient. The expression recipient is important in this matter. As per the Act 2(93) a recipient is known to the person who is liable to pay the consideration, when consideration is payable for the supply. – Based on the invoice the consideration is payable. Therefore, the Bill to the party to be considered as the recipient.

Incase of 10(1)(c) the POS will be the ‘location of the goods’ and in case of 10(1)(d) the POS will be ‘site’.

Therefore, as far as the GST partner is concerned it can be ‘bill to party’ or location of the goods’ or site’ as the case may be.

When MIRO is created, in SAP, the invoicing party PI partner function will regulate the tax from region and the plant controls the tax to region. Therefore, the plant region is copied in PoS field as the tax to region. For tax calculation standpoint, the GST partner’s Region will be used. In such cases, the user will be equipped with the provision to alter the GST partner and Place of Supply in MIRO also.

Incase the user wants to use any other party for GST calculation in an automated way, they can generate an implicit enhancement to the FORMs ‘GET_GST_PART’ and ‘GET_PLC_SUP’ under Function group ‘J_1IG_VENDOR_SUBSCR’ and alter the values within the enhancement as per their individual requirement.

In Purchase Order, the tax calculation can be predisposed by using the user exit ‘J_1I7_USEREXIT_FILL_KOMK_KOMP’

In sales also on a similar note, the bill to party is considered as GST Partner and hence tax to region i.e. Place of Supply. All of this can however be altered at the customer’s end by using Badi J1IBADI_INDIA_GST_DETAILS_POST.

For Sales order, Method ‘REDETERMINE_GSTPART_REG_PRI_SO’ of this BADi can be used to modify the GST Partner and Place of Supply.

In Billing, Method REDETERMINE_GSTPART_REG_PRICNG of this BADi can be used to modify the GST Partner alongwith the Place of Supply for Tax determination. In Addition to all this, the passing different GST Partner and Place of Supply to Accounting interface, Method REDETERMINE_GSTPART_REG_ACONTG of this BADi should be implemented.

For GST Localization, which all SAP modules are in scope?

The modules supported for GST are

  • MM
  • SD
  • FI
  • SRM
  • CRM
  • Real Estate

All other module for example - IS Retail, Asset Accounting, FICA, DBS, Warranty Claim, FSCM, Transportation etc. are out of scope

Are the evaluated receipts settlement (ERS)/ MRRL maintained for GST?

No, all of these functionalities have never been reinforced for India and these will also be applicable for GST too.

Why are only the Enjoy Transactions are protracted for GST?

Enjoy transactions are basically related to those invoices and corresponding credit memo only (i.e. FB60/65 FB70/75) and these will be extended with GST specific fields. Classical transactions like FB01 are not limited for Invoice and therefore will not be extended by these fields.
