There are no business transactions assigned. Behavior is determined by the object type QIN. If you go into the profile QM_P_001 then select from the Menu: Extras-->Object Type Inf and enter QIN in the object type you'll get the following info.
So the object type does not allow the control of business transactions.
Also, read the confguration text docment.
You'll see the status profile is primarily used to change the applicable inspection types. Each inspection type can have it's own settings including unique task usage.
Each time an acceptable UD is made, the status is advanced by one.
You assign each status in the profile to a specific inspection type.
So you can progress the relationship through progressively less strigent testing requirements. I.e.
inspectoin type 1001 has a task usage 101, the plan has 30 tests on it.
inspection type 1002 has a task usage of 102, the plan has 20 tests on it.
inspection type 1003 has a task usage of 103 and the plan has 5 tests on it.
If you want to do say three rounds of testing at a particular stage you need to put in three separate statuses, one for each round of testing. In the SAP example they only have it set up for one level of testing. Using the above example, to have three rounds of testing at each level you would create a status profile with 9 levels.,
The first three statuses would be assigned inspection type 1001.
The second three statuses would be assigned inspection type 1002.
The last three statuses would be assigned inspection type 1003.
You would then have one more status which would be the normal production testing and would either not specify an inspecttion type, (defautls to 01 variant or the one marked as preferred), or could have a special inspection type assigned.
For the specific question above on understanding how to use QM_P_001 please read the configuration documentation carefully. The example that is presented and described in pretty good detail in the config documentation explains the QM_P_001 in pretty good detail.
The main detraction from this process is that you can only have one active inspection lot at any given time. The system blocks any future GR's until the UD is made on the previous receipt until you reach the final status. Which is often impractical in many companies. For instance, often times qualification samples are sent in all at once so you'd have three batches of test batch samples received at one time. There is a weird way around this involving security that is explained in the config document. But I think it would call the standard 01 default inspection type which would probably not work for most people as it defeats the purprose of the status profile to progess through the various inspection levels.
I hope this helps.
