st: Re: Type Miismatch error after Encode in time series

["Sergiy Radyakin" <Radyakin@aoek.uni-hannover.de>]

Hello Michael,

after -encode- your cust_id variable is numeric.
It makes no sense to compare it with a "STRING".
Use your original variable customername or the
corresponding numeric value of cust_id.

Regards,
  Sergiy
