error: server was unable to process request. --> value can n

Hi All,

PowerBuilder <--> Web Service <--> SAP

1. Web Service <--> SAP

I created web service which is consuming SAP service. When I am giving the input XML then I can access SAP data in my service and getting the output as per expectation. Working fine.

2. PowerBuilder <--> Web Service

I don't have power builder code. I have only deployed file. I changed service URL (http://10.10.10.10/myservice.asmx) in power builder ini file. Now I am getting error: server was unable to process request. --> value can not be null. Parameter name : s

I fixed same issue previously, I removed authentication from IIS and It was working fine.

Please help me out, I am unable to fix this bug. Issue is not related to parameter, I am 100% sure for that. Please let me know the step to make web service public, so anyone can utilize it, outside entity also.

Thanks in advance,

Regards,

Rohit
