Conditional Output error for 'Interval values allowed' Characteristic

Dear Experts

If a characteristic has the 'Interval Values allowed' box checked, the WWI code with conditional output using  comparison operator  GE(Greater Than or Equal to),gives error while checking the template. Is there any other way to overcome this constraint ? My requirement is to output concentration values only if they are greater than or equal to 1%.

To some extent similar scenario mentioned  in SAP help.   I checked few threads with similar issue but want to avoid the option of  creating customized characteristic with  Int val allowed box unchecked.

Example: Conditional Output with Alternative - Basic Data and Tools (EHS-BD) - SAP Library

Your suggestions are welcome.

Thanks,

Ashish
