Similar to an Implementation layer Agent, the Access Group specified by your Service Package has to have access to the rulesets in your Implementation layer in order to create an Implementation layer case.

The other way around, an Implemetnation layer Service can always call a Service Activity that is defined in lower layers, e.g, the FW layer.

Technically you could have an FW-layer Email Service Package do everything in terms of incoming email handing but each Email Service would have to immediately queue anything meant for the Implementation layer.

An Implementation layer agent would then read from the queue and perform the indicated processing, but this would not be as efficient.

Hi,

 I have few question to keep service pack in FW layer. Service Pack rule, we need to mention AG, Which would be used to requestor to locate all rules based on rulset stack. 

Let assume, we  have ABC-FW-SampleFW-Work , ABC-IN-Sample-Work, ABC-US-Sample-Work as layers. If I keep service Pack in FW layer. If I mention SampleFW:Admin as AG for service pack.

When send email to INEmail, USEmail, how system will identify rules are in IN/US layers since AG is from FW.

Thanks
