Process of Manual Rebate Agreement Recalculation

On the Rebate agreement detail page, there are 2 buttons, which cause document recalculation. The difference is in how many lines are calculated.

Recalculate - all line items are recalculated
Recalculate Changes - recalculate only the line items, which have some changes against the previously calculated version. (Note, that the button is on the line item’s panel with input parameters.)

A change of the line is, for example:

A line item has field dirty, which is set by system to true for each line, which should be recalculated.

If you want, you can read the value of the item’s dirty field in the header logic’s post-phase, and do only processing of the recalculated items.

The user clicks on Recalculate or Recalculate Changes
The system calls the Rebate header logic in pre-phase
- usually the header logic creates input fields on the header, but can also change the structure of the document
The system sets the dirty flag for line items, either for all or only for the modified ones
for each "dirty" item the system will
1. call the Rebate calculation (item) logic (only elements from group agreement)
2. take the logic’s element results, and store it on the line item
the system executes the header logic in post-phase
- usually the header logic calculates some summarized results and creates the result fields
the user can see the recalculated results on the detail screen
