"{?Pm" in Select Expert 1

[DilbertAsok]

Hi,

I'm making changes to a Crytal Report that was written by someone else, and within the Select Expert section there is the following formula:

{TABLE1.CODE} = {?Pm-TABLE2.CODE}

What does the

?Pm

mean or do?

Thanks,

You are working on a report that is a subreport within another main report. The {?pm-Table2.code} represents the link to the main report field {table2.code}.

That makes sense, thanks.

I have since noticed that I can set the link between the subreport and the main report when I first go Insert>SubReport, but can I amend this link at a later stage?

As it is my subreport was very simple so I just deleted it & made another, but this would be good to know for future reference.

Thanks.

In the main report, go to edit->subreport links and change the links there. I would then double check the record selection formula within the subreport to make sure that old links are removed and new ones reflected.
