Help! Unable to load SAP package!

I have unzipped to directory “Integration_server\packages”, then restarted integration server, but it showed “Unable to load SAP package,(possibly due to circular dependencies)”. why? I can not find wmPartners directory under “Integration_server\packages” too.

The WmPartners Package is a prerequisite for the SAP package. If you don’t have it yet, look on the webMethods download site for it or ask your webMethods support. It should be available for free. Install and activate it and then try to activate the SAP Package again.
