Making fields required in ALM?

Hello, We have a need to make fields in the ALM Requirements section as mandatory and required when creating or editing requirements. We have tried to customize the workflow but are unsure as none of our customizations are taking. We are trying to make the fields required by using changing the fields to make them required: Req_Fields.field("RQ_TARGET_REL").IsRequired=True Req_Fields.field("RQ_TARGET_RCYC").IsRequired=True However this is not working. Any help would be appreciated, HomerJ
