VERIFIED SOLUTION i
When using the Spectrum Miner (Formerly Portrait Miner) Data Build Manager, the browse option for Value field is disabled/greyed out in Data build manager and the user is not able to change the value in the test field.
The Value field browse option is only valid if there is a pre determined set of values for that field
ResolutionUPDATED: September 27, 2017
If the browse option for the Value Field is disabled then we can type the text manually and pressing Enter will force the qsbuild string to accept the text we enterd in the Value field.
