Hi @Phillips, Keith
Lookup fields in SharePoint allow users to select a value from another list, which is then linked to the current list item. Lookup fields are used to create a relationship between two lists. CAML (Collaborative Application Markup Language) is an XML-based query language used in SharePoint to query data from lists and libraries.
Let’s filter projects by parent project lookup field value “Address Book”. Here is the SharePoint CAML for a lookup field.
<View Scope='RecursiveAll'> <Query> <Where> <Eq> <FieldRef Name='ParentProject'/><Value Type='Lookup'>Address Book</Value> </Eq> </Where> </Query> </View>
