As of today 5/6/2019, Anaplan does not allow you to transfer values of a line item with the dimensionality ofUsersto another of different dimensionality (say,Custom_Users), even with the use of a mapping (lookup) fromUserstoCustom_Users. The reverse is permissible: if the source is a line item of dimensionalityCustom_Users, it can be brought into another with dimensionalityUsersusing a mapping (lookup) fromCustom_UserstoUsers. There's a distinction to be made, as sometimes, you do want the final working dimension to be a normal non-Userslist (since that has a top level, etc.). In that case, the process would have been 1) input usingUsers-dimensioned line item, 2) transfer toCustom_Users, and 3) do calculations and reports usingCustom_Users. Again, as of writing this is not permissible.
I offer two workarounds:
1) Run an import process that transfers data from theUsers-dimensioned to theCustom_Users-dimensioned.
2) UseCustom Usersas the dimensionality, applying a filter with dimensionalityCustom_UsersxUsers(TRUE ifCustom_Users=Users). This ensures a User can only see his/her correspondingCustom_Userslist element.
I will be first to admit that neither are perfect, 1)'s disadvantage being dependence on a process to be run, and 2)'s disadvantage is requiring aCustom Usersmaintenance toUsers, though this can be solved easily by using the same coding and doing afinditem. Let's hope some enhancement comes its way.
