Resolve issue where inverting a record selection twice on a binary integer field loses the selection in Spectrum/Portrait Miner

Issue

After inverting a record selection on my 'Flag' field twice, it seemed to lose the selection and all my records were selected again.  Why?





 

Cause

A bug exists within the Decision Studio component of Spectrum/Portrait Miner, whereby inverting a record selection twice on a binary integer field will completely lose any selection on that field.

It is possible to invert a record selection on a field, using the Invert button  Invert button in the Select Values window.

Note that inverting selections works correctly on other non-binary numeric, categorical and date fields.

Resolution

UPDATED: August 1, 2017


If a record selection has been lost, it should be applied manually again in the Select Values window by setting the upper or lower limit as required:
