Please help.

Right now, you are suppressing individual fields if the data in that field is duplicated. What you want to do is group your data.

1. Goto Report->Group Expert
2. Add the grouping field (in this case, probably subitemcode)
3. Move IsLock and SubItemCode to the Group Header section.
4. Right-Click->Section Expert to suppress the Details and Group Footer sections.
