Problem with cross tab report in report viewer

Asked by: NataliaT

I have Crystal report that uses cross-tab. It runs fine when I preview it within Crystal reports, but when I view it with web viewer I get error:
Exception in formula '{@displayString}' at '9999999': A string is required here.

I get this error only  when I have numeric values in  cross-tab report.

What is @displaystring (code please)

 

by: NataliaTPosted on 2009-09-14 at 09:42:39ID: 25327148

I don;t know, this is what browser shows. I do not have filed or parameter with this name

 

by: LinInDenverPosted on 2009-09-14 at 10:15:18ID: 25327417

It sounds like you need to convert @displaystring to text. This should handle numeric strings properly.

totext({datafield}) <-- should be in your @displaystring formula.

 

by: LinInDenverPosted on 2009-09-14 at 10:16:46ID: 25327430

If you are using a field directly from your database inside the cross tab, you should create a formula using what I described above and use it in the cross tab instead. This way you can force the sub report to always see the value as a string instead of a number.

 

by: NataliaTPosted on 2009-09-14 at 10:17:37ID: 25327443

I do not have @displaystring formula in my report otherwise I would do that already

Right - as a I mentioned in second post.
If you are using a field directly from your database inside the cross tab, you should create a formula using what I described above and use it in the cross tab instead. This way you can force the sub report to always see the value as a string instead of a number.

Something else that might help you - Export the Report Definition (it opens as a text file and contains all information about the report) and search for @displaystring to make sure it isn't an old reference in the report.

 

by: NataliaTPosted on 2009-09-14 at 15:09:18ID: 25329804

I've changed fields formatting to text and it works.
 Interesting suggestion to export report definition, but I cannot find how to do it. I have Crystal reports XI.
Thank you.

 

by: LinInDenverPosted on 2009-09-14 at 17:32:36ID: 25330470

Natalia - it is from the export (in the same place you go to export to PDF) - choose Report Definition.

 

by: louisghPosted on 2009-09-15 at 01:53:56ID: 25333004

I think that maybe you should try to terminate Null values for one field or more..
by replacing the field with a formula with if statement that returns blank or zero if it is null..

the viewer show an error in Null values !!
