WhilePrinting & WhileReading 1

[CTLReporting]

Could someone please explain these two? And the advantage they have over just using forumlas rather than defining when they run during the report?

I know WhilePrintingRecords runs AFTER the database read, and WhileReadingRecords runs BEFORE the printing of data. If I am wrong with this, that could be a reason why I don't really know any use for these two functions.

The advantage of using "WhilePrintingRecords;" is that it ensures the formula evaluates in the order that the records show on the report.
This is useful in cases such as a formula referring to the previous or next record values (using the Previous() or Next() functions).

One of the typical suspects you should consider when a formula is returning unexpected results is that perhaps you need to insert "WhilePrintingRecords;" in it...

The advantage of using "WhileReadingRecords;" is that since the formula is evaluated early, it is available for early actions such as record selection formulas.

Sounds Good, and since I have yet to do any work with previous or next or had any need for formulas in record selection, that is probably why I do not know much about these two functions. (I've only been working with Crystal for about 3 months)

Thank you for your explanation.

And I would just like to say this forum/website is amazingly fast. And I prefer it to the Crystal Decisions web forum. I've had 2 questions answered in a matter of minutes before I have had one looked at on the crystal forum. The members here are so much more professional and educated. Cheers to All!
