How To

SharePoint Lookup from a SubSite

Sometimes you may need to specify a specific URL to the SharePoint list you want to perform a lookup on, if that list is not in the site specified in Data Source A. For example if Data Source A was running in a sub-site of SharePoint and the required list is located in the root site of SharePoint Data Syncs Lookup functions can handle extended formats that override the settings that are typically gathered from the data source properties. Using calculated columns we can use the LOOKUP function to pass the SharePoint site as part of the expression.

Syntax

LOOKUPA(string column, FROM(KV(string parameter, string location/url), KV(string valueParameter, string valueName)), WHEN(string value, object))

Inputs

Object Data Type Description
column String The column name to find.
parameter String The parameter to override.
location/url String The location to find the parameter to override with, e.g. a URL.
valueParameter String The value you are looking for.
valueName String The name of the valueParameter you are looking for.
value String The value you are looking for.
object String The object you are looking to match the value to.

Example

In this example we can get the User ID from the User Information List in the root site whilst running in the sub-site.

LOOKUPA("ID", FROM(KV("SharePointUrl","https://simegoltd.sharepoint.com/"), KV("ListName","User Information List")), WHEN("Name",Title))
