Manish, My technical has reviewed the ROCS utility. Few observations, there is no ability to provide list of entities or crosswalks to update it will do all where it find the Attribute you are wanting to update. When he did a small test, it clears the value from surviving in the OV, however the value is still present on the Crosswalk, it is just no longer considered in the OV. We need to update profiles where entity type = HCO, and DistributorName = LegacyData and OV_Source <> 'Gaine'. Ultimately want to Delete the attribute not just clear it or stamp with ignore. Are you aware if this ROCS took can do that and if you can specifiy via criteria the exact profiles to remove the attribute from?
