Help with Patch formula on form with 3 data sources

Hello PowerApps power users...

I've been working on a PowerApps form SharePoint integration for awhile but can't seem to find the correct formula so that the SharePoint form fields submit back to the form as well as fields pulling data from other sources: the SharePoint form data, a second SharePoint list and a SQL database.

 

My formula looks like this: (with the specific fields within the patch referring to the second/third data sources)

 

Patch(

    NEWEscalationRequest, Defaults(NewEscalationRequest),

    {E365Account:E365Account_DataCard2,Product:Product_DataCard2, E365UltimateID:E365UltimateID_DataCard2.DataField,EnterpriseSuccessManager:EnterpriseSuccessManager_DataCard2.DataField,SupportAccountManager:SupportAccountManager_DataCard2.DataField,ProductID:ProductID_DataCard2,ProductManager:ProductManager_DataCard2.DataField,ProductBrand:ProductBrand_DataCard2.DataField

    })

;Navigate(Complete, None)

 

I was surprised that the Product data card would not accept anything after the dot(.) and did not throw an error when left without a control name.

Here is an example of two fields pulling from a separate data source

  • Products field: Sort(Distinct('[PROD].[Products]',Name),Result)
  • Product ID field: Filter('[PROD].[Products]', Name = DataCardValue12.Selected.Result)

Currently, the form submits to list with only the SharePoint list fields populating.

Any guidance very much appreciated!

Yes, because we need to have your form actually get those values from the place you want.
Each DataCard in your Form will have a DataCardValue control.  It is that control that we are concerned with setting the Default values.

So, in the case of your Product...you say that is based on a SQL Database.  I assume that it is that input that then determines the values for ProductID, ProductManager, and ProductBrand.  So, assuming that is a Text column and you have a Textinput control for the DataCardValuexxx  in that datacard, its Default Should be set to Parent.Default.  

 

For your ProductID, the Default on that DataCardValue control would be:

   Coalesce(Parent.Default, LookUp(yourSQLList, Product=DataCardValuexxx , ProductID))

 

This will display the stored ProductID from the SharePoint list when you are editing a record, otherwise it will show the ProductID from the SQL database when you are creating a new record.  

 

Replace the names above with names of actual controls and fields in your app.

 

Your original Patch was not pushing values to your list, most all of your columns were using the DataField property, which is just the name of the field for the datacard...not a value.

Can you describe more about your scenario?

1) Where is that formula you posted located in your app?

2) If you are using a Form, where is the SubmitForm function?

 

In general, your formula should not be referring to datacards, but instead to their inner controls and their values.  However, in the context of a Form, this should be done from the LastSubmit value and NOT from the controls themselves as this can lead to issues.

If you want to submit to both a SharePoint list and a SQL data base then you'll need to use two separate Patch() statements.  You can't submit to two data sources with a single patch().

Sorry to leave out that info:

1 -  formula is on OnSelect property of submit button

2- i left out submitform function, thinking that would cause duplicate items (submit form + patching defaults?)

 

Thanks for the clarification regarding datacards vs. inner controls

I want only to submit back to the original SharePoint list but just populate a few fields in the form with data from a database.

@acoliva 

Your form is only going to be based on one datasource.  You will need to submit that information.

Your OnSelect of the submit button should be:  SubmitForm(yourForm)

 

As for your getting values from other sources, this should be a function of each individual field that you want to get that value for.  Not in your submit. 

 

Can you provide more details on which fields you are trying to get values from other sources?

If you want to get some values from a SQL database to submit to certain fields in a SharePoint list using Patch then you have to reference those fields from the SQL database, not from the datacards in a form.  If you have a connection to the SQL database you should be able to do a lookup to get the record and then access the specific field value you want to submit using Patch.

There is no need to perform a Patch in a separate step.  You can get all the values you need from your SQL datasource into the datacards of the form and the SubmitForm will perform the rest.

For example, if you have a column in your Form called CustomerID and this value comes from a SQL DB called customers and is based on the Company Name, then you would have the CustomerID field in your Form and set the DataCardValue control in it with the following default property:

Coalesce(Parent.Default, LookUp('[dbo].[Customers]', CustomerName=datacardValuewithcustomername.Text, CustomerID))

 

That is all you need, you now have the customer ID in the form and it will be submitted properly to the list with a SubmitForm.

I agree that a Patch isn't necessary.  But the original question was how to do it with a Patch.

I must be doing something wrong then. On both the testing play button and in the live site when filling out the form, all my fields render successfully (as you mentioned using the filter properties etc.). I see them all appear in the form. But when I strip out my patch and just use SubmitForm function, the only fields that populate in my list are the ones from the original SharePoint list.

Thanks for sticking with me.

 

Regarding your question of which fields are coming from other data sources:

  • E365Account = 2nd SharePoint list
  • Product = SQL database
  • E365UltimateID-based on E365 Account field
  • EnterpriseSuccessManager- based on E365 Account field
  • SupportAccountManager- based on E365 Account field
  • ProductID- based on Product field
  • ProductManager- based on Product field
  • ProductBrand- based on Product field
