@softec17 @sravya to create a Scripted Field, you select Management -> Index Patterns
And then Scripted Fields -> Add Scripted Field
If you create a scripted field with a Type of "string", a Format of "url" and the Script of: 'http://testwebsite.com/' + doc['geo.dest'].value + '/' + doc['geo.src'].value
it'll create a URL using two fields from the document
