Field Estmated cost in Maintenance Order Screen

Dear friends,

When our user creates Maintenance Order via IW31 OR through Maintenance Notification IW22,

there is one field available as " Estimated Cost " where user gives input some value.

Once this Order gets released via green flag and saved, this field went into GRAY MODE.

Can not change the value.

Users wants that even after release of Maintenance Order, this value of Estmate Cost field

required to be changed because there are possibilities, user gives input value wrong when

Order gets created.

Please advise.

thanks and regards,
