VPRS condition amount is converted to sales unit in invoice

Hi All,

I have observed that in the invoice VPRS amount is converted to sales unit though the standard price in material master is maintained at base unit.

Example:

Sales order

VPRS

Amount = $4281.91 for 10000 EA

condition value = $693.83

Qty = 18 CA  (90 EA = 1 CA)

Invoice

VPRS

Amount = $38.55 for 1 CA

condition value = $693.83

Qty = 18 CA  (90 EA = 1 CA)

the problem is when if I create a return order with reference to Invoice, its copying the VPRS condition amount from invoice and because of that the total condition value is not matching between sales order and the return order

Example

Return order

VPRS

Amount = $38.55 for 1 CA

condition value = $693.9

Qty = 18 CA  (90 EA = 1 CA)

there is a difference of  $0.09 coming between sales order and return order due to rounding problem.

Please let me know if there is any way to display amount for 10000 EA in Invoice.

Thanks in advance

Regards

Suresh
