Validation rules-comparing the field from one custom object with another custom object field

Hi all,

I am having two custom objects which is named as custom_object1__c,custom_object2__c.Now i want to write the validation rule on custom_object1__c saying that "custom_object1__c.transactiondate  should be always greater than custom_object2__c.somedate".

 

I have written the validation rule like this.

transactiondate__c < custom_object2__c.somedate__c

 

I am getting the following error.

Error: Syntax error. Found 'custom_object2__c'

 

how can i write the rule for this scenario.

please help me to solve this.

 

thanks,

Arun.

Hi Arun,

 

To access the information of Object2 in validation rule on one object1, there must be relation like Lookup or Master-Detail between objects. If there is not any relation then use trigger on Object 1 but also make sure that there should be one field on both object that corresponds both object records.

 

Let me know if you require trigger.

 

Thanks

Hi,

 

I think there is Lookup or Master-Detail Relationship between Object 1 and Object2. If yes then access corresponding field of Parent Object by relationship name as following.

 

transactiondate__c < custom_object2__r.somedate__c
