Is ITK provide any way to restrict the Export Data size apart from time duration

Hi Team,

I have following question on Ariba ITK utility,

• Is there a way to restrict the size limit at ITK on the Exported Data. I could see that based on the time duration we can some how restrict that but apart from this is there any other way.
• Do we have way to know like if there is any new Purchase Order created in Ariba so that we can call Export operation for that duration only.
• Do we have any limit on the data getting exported from Ariba.
• Can we receive Purchase order from Ariba using web service/ITK  one at a time.

Thanks,
