Hi Experts,

Our user claimed that the “No.” value of Sales Invoice/Purchases should be the same as the “Pre-Assigned No.” after posted. Currently system move the value of “No.” to the “Pre-Assigned No.” field and assign a new “No.” value by using the “Posted Sales Invoice”/“Posted Purchase Invoice” no. serious. Are there any simple setting that can change this design?

Please help!

Thanks,  
Noel

Hi Noel,

If you assign the same No. Series to both Invoiced No. and Posted Invoice No. it will use the same reference.
