I have an validation rule on the Opportunity Object which disallows reselecting previous stages based on stage values from 1-8.
These are my stages:
01 - Identifying an Opportunity Open
02 - Determining Problem, Impact, Ideal
03 - Validating Benefits & Value
04 - Confirming Value with Power
05 - Negotiating $$ & Mutual Plan
06 - Finalizing Closure
07 - Pending
08 - Closed Won
08 - Closed Lost
08 - Closed Lost (alternative Quote)
And this is my validation rule so far:
AND(
(PRIORVALUE(stage_value__c) > stage_value__c),
(PRIORVALUE(stage_value__c) = 8)
)
As you can see I have several values in stage 8. Now I want the user to be allowed to change values from stage 8 to another stage 8 value.
How can I archieve this?
