I have 2 lists in Sharepoint:
BasicInfo (ID, Name, CompanyName)
COVIDResponse (basicInfoID, Question1, Question2, Question(n+1) ..)
I have set COVIDResponse.basicInfoID to be a Lookup against BasicInfo, and set this as a required field. On the sharepoint end of things, this works great - I must enter the data in BasicInfo first, then I am able to create a row in COVIDResponse - first selecting the correct basicInfo record before being able to create the COVIDResponse record.
I am trying to make a Powerapp for my users to use. I've created the BasicInfo form without issue - data submits, etc.
On the next screen, I want to present the COVIDResponse fields. Since I've made COVIDResponse.basicInfoID required, I need to know how to set it from the BasicInfo submission.
I have tried following https://wonderlaura.com/2017/08/16/powerapps-set-sharepoint-lookup-field/, but she's pre-populating (and pre-selecting) a field in a select list. This method didn't seem to work in my application.
I have tried using the Lookup() function (following loosely on https://powerusers.microsoft.com/t5/Building-Power-Apps/Auto-populate-fields-based-on-the-users-inpu...) by settings the Items value to "LookUp('Basic Visitor Information', ID=BasicVisitor_Form.LastSubmit.ID)", but this resulted in an error - Items is looking for a Table value, and lookup returns a single record.
Solved! Go to Solution.
Correct - 2 forms, on 2 different screens of the app. 1st form sets varLastSubmit onSuccess, and 2nd form is the one generating the error when I submit the form.
I added a custom datacard to the form, and set its datafield to "BasicVisitorID".
I added a TextField to that card, and set its default value to "varLastsubmit.ID".
When I move from the 1st screen to the second screen, I see the generated ID in the textfield. Upon submission of the 2nd screen of the app is where I am seeing the "BasicVisitorID: Field "BasicVisitorID" is required." error message.
I think you didn't get suggestion. Read my last message again. Delete the Datacard which is a dropdown and insert a new one, this time not a dropdown but with just a textfield. After deleting, it be as if you are now adding a new field to your form.

I don't get a choice as to the field type when I add the field - I am adding a field from a data source, and it comes in predefined as complex.
I found a thread at https://powerusers.microsoft.com/t5/Building-Power-Apps/Set-Default-Value-for-Lookup-Field-in-New-Fo... describing the exact problem I am having, and applied the solution there. Seems to work so far!
