* To make it simple create a form with form wizard for invoice table
* And name it "invoices"
* Set datasession to 2-private
* Select form\New property
* Add a new property named "pkey"
* Open dataenvironment and set filter to "pkey = thisform.pkey"
* Dblclick on form to open code window and select init event on right combo
* write these (assuming your key field for invoices is pkey)
lparameters m.pkey
thisform.pkey = m.pkey

You will call this form like :
do form invoices with m.Pkey
where m.Pkey is the pkey for invoices you want to see.
