PM52378: "IMPOSSIBLE CASE IN FILE "AT_COMPONENT_VARIABLE.CPP", LINE 84" ERROR BUILDING CHAID MODELS

APAR status

• Closed as program error.

Error description

• You are building CHAID models and when you try to build models
  on certain data you see the following error when you execute the
  model builder:
  
  "Impossible case in file "at_component_variable.cpp", line 84"
  

Local fix

• This is caused by input variables to the model builder of
  date\time\timestamp storage and nominal measurement level.
  date\time\timestamp fields are not supported for tree models and
  if they have continuos storage they are filtered out when you
  execute the model builder - and messages to this effect written
  to the execution log. If such fields have nominal storage they
  are not being filtered out when they should be, resulting in
  this error on execution.
  
  This is targetted for fix in 14.2 Fix Pack 3
