SharePoint List Input - Issue of data type

6 - Meteoroid

I connect with SharePoint List, connected fine but seems like datatype is not supporting 100%. I mean to say, Field1 is auto selected for data type V_WString (20), but I found there is many records have more than 20 chars in Field1. While running workflow, it throws warning of truncation. There should be a way to set Data type of Input source.


There can also be possible, when SharePoint List source is connected in Workflow that time there was only data with less than 20 chars, but after expansion of data in SharePoint List, there is more than 20 chars for the same field which will end up with truncation.


Does anyone know how to take care of this issue? Thanks.

If you connect a Select tool after the input, you can easily modify the string type to a larger number of characters.

I thought same way and added select tool after SharePoint Input, and changed data type with larger size, still same issue. Please find below screen shot. Is there any other solution for this, please? Thanks for your help. :-)

I had a similar issue and found that it was the result of a linked sharepoint field (choices) and an entry that did not exist in the available list. For example, "Round Trip" vs "Roundtrip". I corrected the missing entry and Alteryx stopped truncating the data set.

That's right. I also done something similar, and also added one dummy entry with expected long enough string, so in future if there is something longer than which is not available right now then also it works fine. Thanks for your response.

Jason, I have a customer that is asking if Alteryx is capable to connect to the 365 Connect site (sharepoint).


I can see the sharepoint connect Input but not sure.

We have O365 version of sharepoint and are running into issues (1 of 2).

Issue 1, confirming authentication, I have domainname\username and that seems to get passed the first error.

Issue 2, we recieve the following "Please enter a valid connection" and the Sharepoint List Input tools says "ERROR: List may not be blank.  Please select a List from Sharepoint."

Any help would be much appreciated.

Thank you,
