im recieving an error message when i try to filter a report on my website project : error message is as follows..
This field name is not known. Error in File C:\WINDOWS\TEMP\rptOrientacionesUsuario {81E783E3-FE97-4126-B09E-AA96E01DA869}.rpt: Error in formula . ' {SISAA.MAESTRO_USUARIOS_SIAL.NOMBRES} = ' ' ' This field name is not known.
 
my code is the following:
 
string selectFormula = " {MAESTRO_USUARIOS_SIAL.NOMBRES} = ' " + Class1.globaluser + " ' ";
            CrystalReportViewer1.SelectionFormula = selectFormula;
where MAESTRO_USUARIOS_SIAL.NOMBRES is the table and field im trying to filter by, and Class1.globaluser is a global string which contains the parameter I wish to filter by. any idea?

The problem is the "SISAA." in your formula. The formula you show in C# doesn't have the "SISSAA." in it. Somehow I think there is a disconnect between your C# code and Crsytal Reports. Somehow the "SISSAA." is sneaking into yoru report and you have to figure out how that is happening.

Ok. If that's the case, then the field isn't recognized by Crystal. The part before the "." is the table name and the part after the "." is the field name. The error message means that either the table name is wrong or the field name is wrong. You have to make sure that your datasource has both the table and field names available for printing.

The error states that the field name is not known. For some reason it isn't recognizing the name of the table or the field. Both that is all I can tell you from the error message given. Sorry.

because look at the syntax on the error... is that right? {MAESTRO_USUARIOS_SIAL.NOMBRES} = ' ' ' is that = supposed to be there?

The last ' is there because CR surrounds the error message with single quotes.
 
What about this, change the formula to hard-code a value you know is in the field. That way you test to see if that works at all.
string selectFormula = " {MAESTRO_USUARIOS_SIAL.NOMBRES} = ' 'Jones'";
Oh yeah - here is how I debug formulas. I FIRST create the formula with Crsytal Reports and make it the way I want it. SECOND, I run the program and go into debug mode. Then I print the formula in debug mode to see how CR stores it internally. I make sure that my formula matches EXACTLY with ZERO variation. Once I get that working, then I can tweak it by adding in variables from my program and make sure that it continues to work each step of the way.
