This article explains how to solve the "InfoPath cannot submit the form because it contains errors" error in SharePoint.

SharePoint, InfoPath submit error, Lookup fields, saving data on Lookup Fields

While using SharePoint and InfoPath, one might encounter problems in saving the data on Lookup Fields. Here we can explore a solution to solve it.

The Problem

While using an InfoPath Form for a SharePoint 2010 List I encountered the following error:


The error is: InfoPath cannot submit the form because it contains errors.

Failed Solutions

I tried with the following approaches and failed:

  1. Manually created the field from InfoPath and assigned a Validation Rule. That failed since the validation rule was not enabled for the field.
  2. Removed mandatory check box for the field. That worked but the customer requires the field to be mandatory. Failed.


The following are the 2 lists included:

  1. Contracts list with Customer Name field and Product Code field pointing to Products list
  2. Products list with Code field

Concrete Solution

The following approach worked:

  1. Removed the field from SharePoint
  2. Created the field from InfoPath
  3. Used Choice field with multiple values
  4. Used Data Connections to Populate field value
  5. Published and Tested
  6. It worked


The following is the procedure to implement the solution.

Step 1: Delete existing field

Delete the field from SharePoint. Save the changes.

Delete the field-row from InfoPath Form. Save the changes.


Step 2: Add Field from InfoPath

Create the field from InfoPath.


Choose "Actions" > "Add Field"

For Data type select "Choice (allow multiple selections)".

Choose "Mandatory" option.

Click the "OK" button to save the changes.

Step 3: Add the Field to the Form

Right-click and add a row to InfoPath form.


Drag and Drop the new field Product Code from the fields list to the form.


Step 4: Add Data Connection

Now the new field and control is missing data-population.

To add a data connection right-click the product code input-area and choose the "Properties" menu.


In the Properties box choose "Get choices from an external data source".


Click on the "Add" button to create the data source.

Choose the options as shown below.



Choose your SharePoint site as shown below.


Choose the Lookup List. (the secondary list from where data is pulled).


Choose the fields to display. (In our case only Code field exists.)


Enter the name for the data connection. (You may use the Suffix as DS.)


Click the "Finish" button to save the changes.


Step 5: Save and Publish

Click the "Save" button and Publish the form.


Step 6: Test the form

Test the form by adding a new item. You should see the item insertion has succeeded without any errors.


You can try with multiple-value checking and being displayed in the view mode too.


This concludes our solution to Lookup field error in InfoPath forms. I hope you enjoyed the solution.
