• Can we create a collection of Maps with different Target Schemas on a Receive Port?
• Why Receive Port and Receive Location can not get a Filter on it but Send Port can get a Filter?

•             Which account do we have to log into to import the decryption certificates to the personal certificate store?
(Local user account/Host service account/Administration account/SSO Administration account)

o             E. To create a pipeline for party resolution.
o             F. To configure the receive location.
o             (A/B/C/D/E/F)

Tracking, HAT

•             What can be the cause of Suspended messages?
•             How we can see the body of the Suspended message?
•             How we can see the context of the Suspended message?
•             You deploy a new version of MyPolisy and want to get the tracking data from it. What you should do? (Choose the new version of MyPilicy in Configuration/Policies window of HAT? Nothing if you also configured HAT to get tracking information from previous version of MyPolicy.)
•             How to see in HAT the tracking data of your policy? (Choose from the “Queries” menu the “Most receive Policy“ command / Choose from the “Queries” menu the “Most receive Fired actions“ command / In “Message Flow” window for the Service Instance which calling your policy you should see the text “Follow this link to view the Policy execution details for this Orchestration Instance“ and click this text)
•             HAT: Menu Operations: Is here data from (MessageBox data base / Tracking data base / both of them / BizTalkMsgBoxDb.Tracking* tables)?
•             HAT: Menu Queries: Is here data from (MessageBox data base / Tracking data base / both of them / BizTalkMsgBoxDb.Tracking* tables)?
•             HAT: Menu Operations: Column "Service Class": Its value can be "Orchestration" and "Messaging". Is the "Messaging" the (Adapter Instance service / Pipeline Instance service / Port service / Port Instance service / undefined)
•             HAT: If the message is Suspended we can frequently see that there are more then one Messages Suspended and related to first Suspended, like a chain of them. Could you describe the situation?

Rule sets, Policies

•             You use in MyPolicy some facts from MyXmlDoc schema. When you are choosing MyPolicy in the Call Rules shape you can not see and choose the parameters of MyPolicy. Why? (You have only one message variable with MyXmlDoc type and it chosen automaticaly / You did not change manualy property the “Document Type“ for facts of the MyXmlDoc schema / You use the wrong version of MyPolicy in Orchestration / You use the wrong version of vocabulary for MyPolicy)
•             You use MySchema in the MySolution.MyProgect assembly and use in policy MyFact that is NodeA under RootNode of the MySchema. What the value should be property the “Document Type“ for this fact? (MySchema / MySolution.MyProgect / MySolution.MyProgect.MySchema / NodeA / RootNode.NodeA / MySchema.RootNode.NodeA / MySolution.MyProgect.MySchema.RootNode.NodeA)
•             You deployed 1.1 version of MyPolicy, then chose MyPolicy in CallRules shape of MyOrch, then you deployed the assembly with MyOrch, and then you deployed 1.2 version of MyPolicy. Which version of the MyPolicy is in use? (1.2, 1.1, you should change the version of MyPolicy in CallRules shape)
•             You use a Policy in an Orchestration. Action in your Rule has changed a value of node in Xml message. How you can get this new value in Orchestration?
(I get it in the Expression shape only if it is promoted. / I get it in the Expression shape anyway by xpath(). / I have to use a variable to pass this value to the Orchestration.)
•             You use in your Vocabulary and Policy class PolicyHelper. You have changed the name of this class to the PolicyOneHelper. What will be going on in Composer?
(Because the assembly name and namespace are not changed, Policy and Vocabulary will automatically change name. / You have to manually change the name in Composer. / You have to manually choose class with new name in your definitions/rules for Vocabulary/Policy. / You could not open those Vocabulary and Policy and will get an error.)
•             You use a Policy in an Orchestration. You start to use new class in your Policy. You have deployed new version of this Policy.
Will your Orchestration work without any error? (Yes/No)
Will your Policy work in the Orchestration well? (Yes/No)
Do you need to manually change an Orchestration? (Yes/No)
Have you got an error if you try to rebuild Orchestration without this change? (Yes/No)
•             How can we track executing of the Rules?
(HAT/Queries/Policies; / load Add-On to HAT then HAT/Queries/Policies; / HAT/choose one of the Service Instance lists ->Right click on one Service Instance/choose Message Flow/choose link "...to view the Policy...")
•             If we open HAT, a window "Policy Execution Details" and go to the one of the windows with the rule execution information (like "Fact Activity") how we can go back and forward between those information windows?
(File / Navigate back/forward; Alt- -> <-; No way)
•             How we can see the working version of the Policy?
(HAT/go to the window "Policy Execution Details"; HAT/Configuration/Policies; in Orchestration click "CallRules" shape and view list of the current policies; in Registry, key "<BREroot>/Policies in use")

Operations, Tuning up

•             Can the message be deleted inside the BizTalk data base?
•             How can we proceed with the Suspended (Resumable) message?
•             How can we proceed with the Suspended (Not resumable) message?
•             How can we repeat the Suspended (Not resumable) message?
•             Does a message, processed but not routed and got to the Suspended state, is goingto delete from the Receive location?
•             How we can get the Suspended message?
•             How we can change the timeout for Dehydration of the orchestration?
