Hi Mangla,
Based on my research, the issue always caused by the data type of input variable mismatch for the Web Service. For example, the input type for web service is String. The variable was of type Object but in fact it was a Decimal stored in it. Obviously SSIS
Web Service Task will not implicitly do a .toString() call on the input variable. So the issue occurs.
To fix this issue, please change the type of the variable. For more details, please refer to the following similar thread:

Besides, SSIS cannot invoke services with spaces in the names. And we should configure the HTTP connection manager the following ways:
Use credentials.
Use a client certificate.
Provide a time-out for connecting to the server and a chunk size for writing data.
Use a proxy server.

HTTP Connection Manager
