id columns have no value in task, calls, events ? I need id in these module table. it is very urgent

I am using Cdata zoho crm api and created system DSN by using auth. token , login id, password. i have linked  all avilable tables to MS Access rdbms. but LU_ZOHOCRM_CALLS is not showing any value. all these is due to empty call id. I am attaching image of table. same problem is coming with tasks, events.
