hello,

We have a new class for creating lookups on reference fields called SysReferenceTableLookup but in cases where we need lookup with fields from multiple fields we can use the FormLookUp option.

You can create a form with multiple linked datasources and drop the fields into the grid view.

Refer to

https://axactive.com/2015/06/14/lookup-form-returning-more-than-one-value/

for formlookups returning the exact required field.

There may be an error for reference table to be the root datasource on the lookup form, so create the form with the table which has the returning value as the root datasource (1st datasource).
