Problem Note 19447: Incorrect Score Code generated from Merge node
 |  |  |  |  |
When using the Merge node to combine modeling results calculated on two or more data sources, the score results might be incorrect. The problem occurs because the generated score code references the input data to each model segment using the same macro variable reference, "&em_score_output". The &em_score_output table for Score Code of path 1 is overwritten when Score Code of path 2 is executed. Values are again overwritten when Score Code of path N runs.
There might not be any indication the code is incorrect since the Score code might run without generating error messages.
The correct behavior is for the Merge node to maintain separate tables for scoring each segment, and then merge the results of each for the final output table.
