Scheduling Agreement

dear friends,

while creating a scheduling agreement, i am getting a message in "create scheduling agreement:item 00010 " screen as " EFFECTIVE PRICE IS 0.00 AND MATERIAL PRICE IS 80". Material price is set by me. If i continue by this i am not able to post MIGO

as it is showing the effective price as 0.00, i am not able to do migo because it shows a error message " traansaction cannot be posted due to error in price determination"

while checking the scheduling agreement in change mode, if i go to items -> condition , i cant c the conditions there. again it shows a message that " not possible to determine condition type.

any clues
