Gst tax payment question

A GST-registered dealer paid ₹3000 tax via SBI, but the amount wasn't reflected in their cash ledger 15 days later. The user is asking for the payment adjustment procedure. Initial advice suggests checking with the bank and raising a query on the GST website. Further guidance depends on whether the dealer is on the QRMP scheme and how they made the payment (monthly PMT06 using fixed sum or self-assessment).
