can we edit a voucher with a wrong percentage allocation copied from PO

Hi,

I have a situation where a voucher has been incorrectly created from a PO line with % distribution.

1. Req total amount= $ 3780873

Distribution line 1= 95% : 3591829.35

Distribution Line 2=5%: 189043.65

2. PO created from req. Total amount=$ 3780873

Distribution Line 1=95% : 3591829.35

Distribution Line 2=5% : 189043.65

3. Voucher created from PO incorrectly.

Dist 1=118959.75

Dist 2=189043

The above voucher is budget checked, matched, posted. Payment is also posted.

Is there a way to fix the distribution % now ?

Thanks,

Debolina
