Hi Santosh,
I think the behavior you are looking for is possible. OCS ships with some SCXML samples which are located in the OCS installation folder.
If you view sample01.scxml it will show you how to go to the next record in the chain.
Additionally, you can form logic around mandatory fields or custom fields. The samples should show you how you can refer to mandatory fields. If you want to refer to a custom field, you first must make sure that send_attribute in section default is defined on the field. Then you can refer to the field like, "_event.data.fields.send_attribute_name".
Additionally, this page may be helpful, it defines some call results and provides some other information:
