DAX Calculate with filter

Hello!

I suspect there is a very simple solution - so embarrassed to ask.  But here goes...

I have a data table showing accounts receivable invoices. For every vendor with EntryType = "R",  - I want to display the "Amount" column, and then offseting pmts.   The challenge is for each InvoiceID, when a pmt is received for that invoice - that InvoiceID is displayed in the description.   For example, (in blue) an invoice was created for Vendor A (InvoiceID = 2888), and then on 1/19/19, a  ROA entry took place, with the description containing 2888.

The example in red, shows Vendor B with an Invoice ID 67408 - and then two partial pmts made against this same invoice.

For Vendor A, the 5400 is the correct amount with only a single invoice and ROA.

However, Vendor B - the current measure is pulling in all ROA's for Vendor B, but ignoring the InvoiceID->Description match.  For invoice 67408 the AcctsRecPaid measure should be $8,000  ($6000+$8000)

Here is my the measure I currently have - how would I create a filter to only pull in Description that equals the InvoiceID.

AcctsRecPaid = calculate([Amount1],Data[EntryType]<>"R",ALLEXCEPT(Data,Data[Vendor]))

I have shared the pbix file if it is needed.   (the data is embedded in the datatable)
