How to add standard fields in Customer Receivable Aging Report?

Dear experts,

I have a problem in showing "Tracking No" from AR Invoice document in Customer Receivable Aging Report.

The case is:

I use the Tracking No ( OINV.TrackNo) to keep real tax invoice number, but Customer Receivable Aging Report is only show automatically docnum from OINV.

Now I want to display this OINV.TrackNo into the Customer Receivable Aging Report.

Any idea?

Please kindly share it.

Thanks
