Importing Cash Receipts Entry with DataPorter in 7.4

I'm hoping someone can assist me with the set up of Metadata.  I'm attempting to import cash receipts using dataporter.  The only piece I have left is how to code Metadata to hit finish.  I was able to key in the tabFunction to apply to the invoice but I cannot figure out how to get it to hit finish and move onto the next payment.  Any help would be appreciated.  Have a great day!
