It is possible that web-service does not run as user that has sufficient privileges/rights. To check it create a method of the COM class, that will return the current context username.
use code like the following:

LOCAL lcUserName, lnLen
DECLARE INTEGER GetUserName IN WIN32API String @ Buffer, Integer @ leng
lcUserName = SPACE(255)
lnLen = 255
=GetUserName(@lcUserName, @lnLen)
lcUserName = LEFT(lcUserName, lnLen-1)
Return lcUserName

If this is true try to give more rights to the user that WEB service uses to get access to the system.
