What is a Test classification actually used for when you generate test plans/packages — and what does it NOT do?

Why does setting a test case's default execution duration matter beyond showing testers an estimate?

Automated test-case generation in SolMan fails until the system is set to Modifiable. Why is client-level changeability not enough, and what extra setting does eCATT need?

TBOM Trace isn't capturing anything during a tester's manual run, even though the case offers the TBOM Trace option. What user-level prerequisite is almost always the cause?

In a release status schema, you want a status that freezes a test plan so its structure can no longer be edited — but testers must still record execution results. Which option do you set, and which one would wrongly block result entry too?

A QA manager wants three different things: (1) are all process steps even covered by test cases/TBOMs, (2) how far along is execution across many test plans, (3) a management summary to circulate. Which of the three Test Suite Analytics reports gives each, and which is new in 7.2?

You bundle automated test cases into a package, define a run sequence for end-to-end data flow, and try to schedule automated execution — it won't run. Why, and what's the constraint?
