SharePoint Lookup

Flinn, Randal J 281 Reputation points


I have a list where employees (Created By) enter records via mobile devices. I would like for a Lookup field (Supervisor) to auto-populate based on the Created By value. My understanding is that mobile devices can't use a lookup to separate list; however, can a record be created on the mobile device and the lookup/auto-populate occur in the "desktop" version (I do not need the lookup value on the mobile device.).


Record/fields entered on mobile device: Created By, Created, Building, Work Performed

Record fields on "desktop" version: Created By, Created, Supervisor (based on Created By value), Building Work Performed

    Hi @Flinn, Randal J ,

    Per my test, the lookup column cannot directly refer to the Created By field in the list. As a workaround, we can use Flow to update the supervisor column. But since the relations between the created by and the supervisor column is unclear, an example will be provided to update the supervisor column with the display name of Created by column. After an item is created, the Supervisor column will be automatically updated to the person who created the item. As it is more related to Flow, if you have other requirements about this task, please reach to Power Automate forum for help.

    Specific steps are as follows:
    1.Create a Person column Supervisor
    2.Create a flow->See your flows->Create: Automated cloud flow->When an item is created->Fill in Site Adress and List Name->New step->Choose Update item->Fill in the appropriate information and select Created By DisplayName in the Supervisor column->Save

    3.Create an item and the Supervisor column will be added automatically.
