  If the following query produces more than one result, that is your problem – you cannot update a single value to a multi-valued result set:

  SELECT DISTINCT
         (e.Id)
  FROM SecurityKmsAbfa..EnterprisePositions e
      JOIN SecurityKmsAbfa..Import_UsersTeh i
          ON e.Name = i.vahedeSazmani
      JOIN NewKmsAbfa..Members m
          ON m.SSN = i.kodeMelli

  Note that the double-dot notation is considered bad practice. Unless you have a reason (other than laziness) for omitting the schema name, it should be included.

  If you tell us what you are trying to do, we might be able to fix your query, but as there are a few tables involved, I'd rather not guess.
