My thoughts 

TGB-Expenses-Work   Expenses: 01-01-05             Withdrawn   ( withdrawn will not be considered)

TGB-Expenses-Work   Expenses: 01-01-03             Available   ( withdrawn will prevent lower version as well)

TGB-Expenses-Work   TGBCatalog: 01-01-05         NotAvailable  ( NA are discarded as part of rule resolution)

TGB-Expenses-Work   TGBCatalog: 01-01-03         Blocked  ( will not be considered)

TGB-Expenses             Expenses: 01-01-03             Final  ( This rule should be picked up )

TGB-Expenses             TGBCatalog: 01-01-05         Available  ( one Blocked version will prevent the rule in higher classes to be considered as part of rule resolution)

Is the reasoning correct?

Hi Swati,

Thanks for posting the query.

As per the rule-resolution algorithm, first, it checks the rule as per the application rulesets hierarchy on considering the higher level of the class hierarchy. As per the above question, am considering the order of application rulesets are

Expenses:01-01-05

TGBCatalog:01-01-05

1. First, it checks the rule in TGB-Expenses-Work   Expenses: 01-01-05, but the status of the rule is withdrawn. As it was withdrawn, even the rule is present in the lower versions of the same class, it won't be considered as per the rule resolution.

As per the above question, the rule is not picked by the rule-resolution in the TGB-Expenses-Work   Expenses and in the TGBCatalog rulesets as well.

2.  As per the class hierarchy, it checks in the TGB-Expenses (Expenses:01-01-03) and it gets executed.

The answer is (C. TGB-Expenses.PopulateLineItems (Expenses: 01-01-03).
