[Back](./) # I’m unable to push an invoice to the IRP because it states that the HSN code entered does not belong to the service. What should I do If you have entered the HSN code instead of the SAC code for a service item in the invoice creation page, you will encounter this error message. To verify the item type associated with the invoice: * Go to _Sales_ on the left sidebar and select **Invoices**. * Select the invoice in which you encountered the error and click **Edit**. The item type will be displayed below the line item in the table. * If you have entered a HSN code for a service item, click the **Edit** icon next to the _SAC_ code and enter the valid SAC code. **Pro tip:** [Go to the e-invoicing portal](https://einvoice1.gst.gov.in/Others/Product) to check the HSN/SAC code of your item. * Click **Save**. After saving the changes, you will not encounter the error message when you push your invoice to IRP.
