looking for best practice calculation to capture variable number of related records as text
I'm looking for a best practice calculation to capture a variable number of related records as text in a single text field. My problem could be conceptualized as needing to take a variable number of Invoice Line items, and present them within sentence and paragraph structures all contained in a single large text field.
I've tried to solve the problem with a layout with portals set to shrink and slide, but it would be better for my puposes to instead display the same lineitems as parts of a sentence, as part of a larger text calculation all contained within a single text field - similar to capturing a form letter within a single text field.
thanks in advance for any ideas.
