I have validation rule on Opportunity like this:
NOT( ISNEW() ) && ISBLANK( MY_Field ) ----- Error Message: Please select "MY_Field" to save this record
It worked fine. Then I created a Process which updates a field on opportunity every time a record is created or updated. Now, when I try to create new opportunity record, I am not able to save it. Below error is generated:
An error occurred at element myRule_1_A1 (FlowRecordUpdate).
UPDATE --- UPDATE FAILED --- ERRORS : (FIELD_CUSTOM_VALIDATION_EXCEPTION) Please select "MY_Field" to save this record.
Also an email is sent which describe the error.
As per the code of validation rule, on record creation this error should not occur.
Any Idea why process cause to fire this validation rule?
