Imcomplete print output for a PO form

Dear All,

I have a strange thing happening to my print preview of a PO which is a sapscript form

Its incomplete .

I have 2 lin items in my PO , only the line item 1 is printing and the rest is blank.

The second line item was added after a few days .

Also there is a difference between the Uom for line item 1 and line item 2.

Line item 1 - H

Line item 2 - DY

Also the material used for both is same and the material does not have the Hour to day conversion.

How to get the full print outout.

Please help

Regards
