I am trying to update a multipicklist field on Accounts using the multipicklist field on Opportunity, which is also using the same global picklist value set. But I am facing two problems with this:-
I am getting an error because of this flow when I try to save a record on Opportunity-- attached a screenshot (This error occurred when the flow tried to update records: INVALID_OR_NULL_FOR_RESTRICTED_PICKLIST: bad value for restricted picklist field:). And also this is not happening for all the picklist values, it occurs for only few set of picklist values.
I am getting duplicate values in multipicklist field on Accounts after the flow is executed as there are multiple Opportunity for an Account. I tried to get rid of that by using decision element that doesn't seem to work.
Pls feel free to ask me anything, if something doesn't make sense.
