The customizable button is useful when you want to call an external program while sending data from EMDI.

#CID   Customer ID
#TEL   Telephone
#MOB   MObile
#EML   E-mail
#ADR   Address
#NAM   Name

When you click on the button having set a web page then EMDI appends the customer id to the end of the address:

Whereas if you call a program 2 fields are being sent:

  1. Customer line number
  2. Customer id


What is being called is defined at settings->customers/suppliers->customizable button.
