Multiple SP lists on one Power App

[maruthi216]

Hello Experts,

This is little tricky, but was thinking of some suggestions.

i have around 400 Columns (Includes Names/Approvers... status/Dates.......) as SP cannot support Max of 258, i was thinking of splitting them into 3 SP Lists.

is there any way i can create 1 App based on all 3 Apps and submit form to all 3 SP Lists...

Thanks

Hi @maruthi216 

You can use the patch function to patch 3 lists one by one but I can only imagine the how long the patch statement would be

Another option will be to create a screen which has all the 3 forms and then when user hits the submit button, you can submit each form one by one

on the comment above...how do i do that..?

Typically i am used to create a Power App based on 1 SP List, how to i go about creating App based on all 3 SP Lists..?

Hi @maruthi216 

This will have to be a standalone App not a SP customized list form using PowerApps

In the standalone App - add connection to all 3 sp lists

[maruthi216]

so just to make sure i am understanding this correctly..

1. i need to build an App from Canvas and start creating all the Datacards.

2. These Datacards should be same as the Column names in all 3 SP lists.

3. Then Using Patch button to submit all these Datacards into 3 SP lists.

Is that correct...?

First I would focus on a better database design :). That many columns is going to be unsustainable using SharePoint lists. Especially if you end up with a bunch of items, you are going to run into view and indexing nightmares. Something more relationable like Azure SQL or CDS seems more fit for the bill here.

Hi @maruthi216 ,

You can always have multiple forms within one standalone app or the custom Form in SharePoint list, and bind each form to its SharePoint list, then add one button to submit  them all at one click:

SubmitForm(Form1);SubmitForm(Form2);SubmitForm(Form3)

Hello Mona,

When you said we can have Multiple forms in same APP, is that some like...

1. SP List-1= Form1

2.SP List-2= Form 2

3. SP List-3= Form3

Is that correct..? if so how can i do that...?

Thanks.

Hi @maruthi216 ,

If you mean to have multiple custom forms for multiple SharePoint lists on one SharePoint list site, then that is not possible. Because SharePoint custom form will have one pre-defined control called SharePointIntegration and this cannot be binded to multiple lists. 

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/sharepoint-form-integration

But if you mean the standalone app, then it is possible. You just need to add 3 different forms for 3 lists.
