In Solidres; there is a plenty of power and control over the tariff issue. It offers "Adjoining tariffs mode" and "Overlapping tariffs mode".
While most of the requirements can be handled using these two excellent features, one finds some situations where none of them will really help.
Example:
Tariff A: Jan 1, 2018 to Dec. 31, 2018 : $ 100 for weekdays.
Tariff B: Nov. 24, 2018 to Nov. 30, 2018: $ 50 for any day of the week.
Tariff C: Aug. 1, 2018 to Aug. 20, 2018: $ 300 for any day of the week.
Since partner has no control over the tariff overlapping and Adjoining modes; we have to check for the expected result:
If Show all was selected: then A, B and C will show simultaneously (bad)
If Show lowest was selected: then B will supersede A (good), But A will supersede C (bad)
If Show Highest was selected: then A will supersede B (bad), But C will supersede A (good)
In my opinion; to provide the best flexibility over the issue, there should be a possibility to select which Tariff plan supersedes?
This can be done by allowing selection from within Complex Tariff framework (see figure).
Hence, if partner did not select any thing (==> normal rules will apply)
If partner selected one tariff-as-superseding (usually shorter period): ==> ignoring normal Tariff rules and applying this currently selected rule).
In short, provide "Front End" partner a more power over the tariff rules of the system.
