Problem Note 31899: Scorecard C score code might produce incorrect scores if numeric class inputs do not have formats assigned in the metadata
 |  |  |  |  |
If you use the Scorecard node in SAS® Enterprise MinerTM to create C code, the created code might be incorrect if numeric class inputs do not have formats assigned in the metadata.
The problem occurs because numeric class inputs that do not have formats assigned in the metadata have a BEST format applied in the score code. When the format is applied, the variable is compared to a numeric value causing an implicit conversion from numeric to character in SAS data step code. This data step code produces correct scores, however C code cannot do this implicit conversion and might produce incorrect scores.
There are no workarounds.
