Provisioning partner (PI client) receives following error message whilst trying to send a Provisioning Interface (PI) request to Service Management System (SMS).


The purpose using a SYNSTAMP is to validate a PI request, it will also avoid any duplicate request which comes to the SMS.

The following rule should be obeyed when the SYNSTAMP is enabled:
  1. PI client should append the SYNSTAMP information within the command,
  2. The next SYNSTAMP must be a number larger than the last SYNSTAMP returned from the PIprocess or used by the user. for example you could take the SYNSTAMP returned by the LOGIN request and add 1 to it for each subsequent request.
