SOAP receiver query

Hi,

I am connecting SAP CPI to a SOAP receiver web service.

But, I am stuck in a requirement.

If SOAP response contains more than 100 employee data, then I have to make another call to SOAP receiver with a fieldname Start=100 , 200,300 etc.. But, How to know that whether the SOAP response has more than 100 fields and how many more call CPI should make.. Is it possible in CPI ?

Regards
