Hi team,

We have a requirement to write a rule for validation at parent entity level. Base levels are divisions so validations cannot work at base level, but it should match at parent entity level. For this we are trying to write a rule at insertion via FCCS _10 and 20 rules, at a parent entity at FCCS_Entity Input consolidation member. Same rule is working for base level entity but not for Parent entity. It is showing #Missing at parent entity member.
