Billed quantity more than Received and invoice is paid

Hi,

 

We have a complex scenario and want to know the best work-around to correct the data.

PO with ordered quantity=1, unit price=1852.04, received quantity=1 and billed quantity=2

invoice created with 2 lines with quantity=1 and amounts 1186.09 and 665.95, both matched to same receipt, so each line has a invoice price variance (i.e. po price - inv line amount)

the invoice is paid (after releasing the holds manually) now user wants to correct the accruals and variances.

"correct the receipt to quantity=2 and manual journals to variance account to negate the variance" is it a good option??

 

I am also dreading about the same scenario for an inventory item, as we use average costing...
