missing data pricing

hi sap gurus,

when i am creating the service order system showing incompleteness in the order missing data pricing. i have checked another order in se16 and found that prsok field is checked with x.

same thing i have checked in se16 for the service order also. and that has not checked with x.

if we can find that prsok field in the order then we can change in the order. prsok field text name is pricing ok.

can anybodu please look into this and guide me how to proceed further.

thanks in advance.
