Dear P'Pen,
For GRN#13551GT we have recorded as per invoices scanned at the beginning.
We unable to record other invoices anymore under this GRN as quantity = 1 has fully utilized.
Please perform new GRN for this.
Note: We always received this kind of issues. 20-30 invoices recorded under 1 GRN with quantity 1.
After we recorded, we still receive another invoices to record under the same GRN.
Could you please scan in all invoices together for this kind of GRN. We do not know whether scan invoices is the final invoice as quantity = 1.
Or could you please perform GRN same as Sangthongsuk which is 1 invoice 1 GRN ( Or 1 GRN with many lines which cover all of your invoices).
Suppose this is the correct process.
