How do you suppress a text object in Crystal if a summarize field inside the text object is equal to 0?
Example of text object content:
I want the text object to only display when {Sum of RETOUR_INVOICE_LINE.AMOUNT_EUR} is zero. It seems I can't select a summary field in the suppress formula editor.
Create a bool formula to be true or false using an if statement in the formula, then you can drop the new formula into the suppression for the field in question.
So a formula similar to this, lets call it fBool_IsZero
if {Sum of RETOUR_INVOICE_LINE.AMOUNT_EUR} = 0 then True else False
Then use fBool_IsZero in the suppression shown in your question.
