Error while creating Variable setDescriptionThe name of a variable set should not be emptyRelease or EnvironmentLondon, MadridCauseThe mandatory fields had been changed on the creation of variable set since London. The message is coming from the OOB business rule "Validate Name". This business rule is active in Kingston but during the upgrade, it needs to be turned into 'inactive'. But somehow it skipped that action(set to false). ResolutionSetting the business rule "Validate Name" on the table 'Variable Set [item_option_new_set]' will resolve this issue.
