What does the abbreviation Arpdi (which comes after my name) on some
bank statements mean? No one seems to know.

Hi cadelac,

  This WAS a tricky one!

  It appears to be an abbreviation used in banking cost accounting
database software, made by Argo Software, depicting the screen name of
a transaction. You can see some screen shots on the link below.

The AR stands for Accounts Receivable
The ?P? stands for  Master menu screen
The ?D? stands for the Accounts receivable menu of the Import Accounts
receivable menu, which is where the ?I? comes from.
Page 12 and 206 display this term. (This is a large download, so be patient!)
