How make subform display only certain records

I have a form that has a sub-form.  When the form opens (with the subform), I want only certain records to display in the subform. that relate to the ID in the main form.  

For of all the link between the 2 form is ID.  

But I want the subform to display only the records that have TRNX_TYPE being "I" (letter I, not 1), and DATE_RECD is not null

Its like the subform should open with:  TRNX_TYPE = "I" AND DATE_RECD is not null

How can I make the subform only display those records?

Add a filter to the subform properties and set filter on load to true
((([TRNX_TYPE]="I"))) AND ([DATE_RECD] Is Not Null)

Or, add a where clause to the datasource query for the subform. If it's currently bound to a table, make the query
SELECT tblTransactions.*
FROM tblTransactions
WHERE (((TRNX_TYPE)="I") AND ((DATE_RECD) Is Not Null));

Which of these options you want depends on your scenario. If you use the filter option, it sets the initial load condition, but users can remove the filter to see the other records. If you do it with a WHERE clause then they can't

Copy the query the subform is based on and call it something like  qTRNX_TYPE_I
Put "I" in the criteria of the TRNX_TYPE field
Put Is Not Null in the criteria of the DATE_RECD field

Then put a command button in the header of the subform that does this in the OnClick Event
Me.RecordSource = "qTRNX_TYPE_I"
