"Component Assignment Incomplete" while Apply Model from ESR

Question

Hi all,
I am trying to configure a scenario by using Model Configurator with Tools->Apply Model from ESR.
My Process integration scenaro is : PAYE_EOY_GB which belongs to the swcv "E-FILING GB 1.0" whose content imported from ESR content available on sap marketplace.
I am trying to configure the scenaro.
The sender is a Business System "Sys_MyECC" which represents SAP ECC.
The reciever is UK govt gateway.. for which i created a party with the name "GovernmentGateway" and a Communication Component "GG_submission" within the party.
When i am in the model configurator, in the step 2 Assign Components, when i am selecting the sender Component as Sys_MyECC,  it is giving the popup message:
Component Assignment Incomplete :
Each business component must be assigned a business system component. Incomplete assignments exist; these can be removed automatically.
What does this message is trying to convey.
thanks in advance,

Besides having a Business System, you need a Business system Service to have a B2B communication
I did not get what exaclty the Business system Service means.
for the sender, we have SAP ECC, the scenario will be triggered using sproxy communication.
so, we created a Business System representing the ECC server.
the "Bysiness system service" means.. does it also represent ECC server, in pi 7.1, if we create Business Component, how we can link the Business Component with the Business system.
