PM61377: MISSING SCORES WITH CASE LABEL SPECIFIED IN KNN MODEL BUILDER

APAR status

• Closed as program error.

Error description

• You are building a KNN model set to "only identify nearest
  neighbours" and using a case label in the model build
  specification. The case label is a typeless field. When you
  build the model and score the data the "KNN-neighbour" fields
  are frequently all empty.
  

Local fix

• This appears to be related to typeless fields being used as case
  labels in a KNN model builder. Overriding the field used as a
  case label to be nominal in an upstream type node and rebuilding
  the model appears to workaround the problem.
