Lookup from another SP List

[Ogun_ustun]

Dear All,

I am pretty new creating power app from and i need your assistance concerning lookup function. I tried to find a solution from internet but even if there are many resource i didn't manage to understand and proceed correctly.

- In my submit from there are "Plants Country" and "Plant Code" fields.

- For instance my company has 3 different plants in Turkey

- My aim is once user select TR from "Plant Country", user should only see TR plants code from "plant code" field

- I have a SP list which includes "Plant County" and "Plants Code" list

How can i proceed related lookup? Which formula should i use in "Plant Country" card which reflects to "Plant Code"

If you review and assist me i will be glad.

Thanks

Hi @Ogun_ustun ，

Did you mean that  "Plant County" and "Plants Code" columns in this edit form are lookup columns? And their source list is EMEA Plants? 

If so, then please also add EMEA Plants list in the data source list of this app. Unlock the data card of  "Plants Code" lookup column, then set below formula in the Items property of the dropdown control:

Filter('EMEA Plants','Plant County'=DataCardValue5.Selected.Value).'Plant Code'

DataCardValue5 is the dropdown control's name in "Plant County" data card.

Then set the Update property of  "Plant Code" data card to:

{'@odata.type':"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",
                        Id:Lookup('EMEA Plants','Plant County'=DataCardValue5.Selected.Value,'Plant Code'=DataCardValue6.Selected.'Plant Code',ID),
                        Value:DataCardValue6.Selected.'Plant Code'}

Regards,

Mona

@v-monli-msftHello

"Plant County" and "Plants Code" columns were added by me in the SP list of power apps as drop down fields. They are not lookup columns.

As mentioned additionally i have EMEA plants list which has also "Plant County" and "Plants Code" columns.

My aim is make a lookup relationship between my app and EMEA plants list but no idea how to do it so since i am pretty new for power apps.

If you review i will be glad
