Variables

rbuser

Is there a convenient way to use a single variable in multiple locations
of a multi-page report? My report needs to print the current year in 24
different locations.

Thanks.

Hi H,

The easiest way to display the current year would be to place a
TppSystemVariable inside your report and set its VarType to Date. Then
modify the DisplayFormat to 'yyyy'.

Perfect! Thanks very much.

Guess I answered a little too quickly. I've just been told that the year
displayed will be based on historical records, so I'm back to having to
deal with a non-system variable. Do I just create 24 variables, ppYear1
thru ppYear24 and make them all equal, or is there anything a little
less brute force?

Thanks again.

Hi H,

I do not believe there is an easier way to go about this other than
placing the number of text components you need and updating their values
manually.

One option to make the updating easier, would be to create a report
object loop that updates all report components with a certain
specification (perhaps "HistoricalYear" in the name). This could make
writing the code to update the values of each year component easier.

Another approach is to handle this from the data side. For example, create a
JITPipeline and define a field called Year. Set JITPipeline.RecordCount to
1. Implement the OnGetFieldValue to return to the year. Then for the report
layout you can use DBTexts to connect to the JITPipeline Year field.

Nard and Nico,

Thanks for the tips and suggestions. Both approaches sound manageable;
Nard's maybe a little less complex. I'll give that a try first.

Thanks again for the assistance.
