Hi David - There are couple of ways to achieve this -
- From Application Designer - Click on Edit Dialog more action and click on Searchmore - More Search Field dialog. You can add field there.
2. Click on Export App Definition and export WOTRACK.xml. You can search for More Search field in it and add tag via XML. Once done Import XML via Import App Definition.
In Maximo 7.6 option is called Advance Search.
In MAS Manage it is More Search Field.
