c# - Crystal Report Chart with Minimum Formula Field Issue -


i'm working on report , satisfied results returning, however, can't chart created how i'd it.

in report i'm looking @ each promotion_content (id) can have 1 or more values in approval stage table (each time approved @ different level inserts line table). want return recent approval stage each promotion_content_id , display in chart percentage @ different stages (approved, unsubmitted etc.).

i've set grouping on promotion_content_id brings 1 or more records each unique promotion_content_id. i've set formula field:

minimum ({benn_promotion_approval_stage.approval_stage},{benn_promotion_content.promotion_content_id})

which brings recent approval stage - looking far. plan suppress details i'm concerned recent approval stage each entry.

the trouble comes when try add field chart, won't allow me add in. explain why , offer solution?

cheers
