Need to write a validation rule if a certain checkbox is check, either one field or another field has to be filled in. So it is one or the other.
To utilize And and OR functionality within the Validation rule.
Create these fields on the Account object or substitute your fields.
Discount Applicable | Attribute: Checkbox
Percentage: Number (10,2)
Error should appear at top of Page stating: Since Discount Applicable is true then Amount OR Percentage is required.
Go to Setup | Customize | Object (Account) | Validation Rules | New
Breakdown the validation Rule:
Discount Applicable = True
This is a must to have so it would go under AND requirement.
Amount is blank OR Percentage is Blank. this is the OR part of the validation rule.
Putting it together:
Start off with OR( then place in the AND functionality within the OR functionality), You can see the formula below where I start off with the OR Statement then the Final should always be there...
ISBLANK(If_Yes_Amount__c), Is_There_a_Discount_Applicable__c = True))
This is it... Hope this helps..
