I’m unable to push invoices to the IRP because it’s asking me to enter UQC. What is UQC and how do I update it?

Insight: The Unique Quantity Code (UQC) is a standardized code that denotes the unit of measurement for an item. It is a mandatory field that must be specified when generating tax invoices, credit notes, or debit notes. The UQC is also required when submitting invoices to the Invoice Registration Portal (IRP), creating e-way bills, and reporting the HSN summary in GSTR-1 filings.

If the UQC is not updated for the item, you will not be able to push invoices to the IRP portal. To add the UQC for the item:

Go to the Items module and select Items.
Edit the item associated with the invoice.
Scroll down to the Unit field and click the dropdown next to it.
Choose Configure Units.
In the Configure Unit page, specify the UQC for the item and click Save.
Click Save again to save the changes made to the item.

Now, try pushing the invoices to the IRP portal.
