QRMP difficult in IFF

One of my client defaulted to deemed QRMP scheme, where didn't had supply or sale except input tax credit. However, later he raised supply of service bill (b2b) for ₹ two crores. My query is when uploading the B2B sales through IFF, it is not accepting. And said that cumulative value cannot exceed ₹50 lakh.
The B2B customer(recipient) paid the amount for the supply, requested to submit GSTR1 for ITC claim in the hands of recipient.
However, Invoice Furnishing Facility is not allow me to file the invoices more than ₹50 lakhs.
What I have to do? If we are not upload the B2B supply more than ₹50 lakh, the recipient ITC is questionable...
