Cyrstal repot viewer bug : errorkind

Hello,

I have an crystal repot viewer application, developed in C++.net platform. My viewer works fine with some reports, but for some reports it throws the next error :

This field name is not known.

Details: errorKind

Error in File : "file path"

Error in formula <Record_selection>

'{V_ADDITIONAL1TODDINFORMATION.CUSTOMER} in ["000"] and '

This field name is not known.

Details: errorKind

I have research the internet for causes and solution but I could not find an clear answer.

What could cause this error for some reports, and what options could i have to solve it ? 

In the development of the application i have used the SAP SDK for .NET and crystal reports XI.

Thanks in advance for your help.
