Business Rules Control Order

Post by PointsWell »

I meant to add this a while ago but forgot.

Business rule execution is completely arbitrary and random, so you have no way to force certain rules to execute in order.

There is a work around though if you add an attribute to act as a flag, e.g. BO.StepFlag. Can either be a numeric or a text attribute with options.

eg StepFlag

Code: Select all

Choice     Value
Start        S
Step1 done   1
Step2 done   2
Complete.    C
Next have your business rules trigger as

Code: Select all

IF BO IS NEW THEN BO.StepFlag='S'

Code: Select all

IF BO.StepFlag WAS CHANGED TO 'S' THEN DO SOME THINGS
BO.StepFlag='1'

Code: Select all

IF BO.StepFlag WAS CHANGED TO '1' THEN DO SOME MORE THINGS
BO.StepFlag='2'

Code: Select all

IF BO.StepFlag WAS CHANGED TO '2' THEN DO THE LAST THINGS
BO.StepFlag='C'
You've now imposed order onto randomly executing business rules.

You can also set the Priority for each Rule to get something important to execute prior to some other Rule.

In on particular BO I ordered the Rules the way I wanted then Set Priority starting at 100 and progressing down in steps of 5 (just in case I wanted to
add a new Rule in between later)

Failing that..... Take all the Rules out and put them in a Process.... This is MUCH faster also as there is no iterative evaluation of the Rules going on.
Just all sequential.
Cheers,
Mark
