Description:
Load data for model building.
Syntax:
ym_model(env,data)
Note:
The external library function (See External Library Guide) loads the data for building a model. The data must be structuralized, and can come from a table sequence, a cursor, a CSV file or a MCF file. When the data is stored in a file, its path can be absolute or relative; a relative path is relative to [sAppHome]/store/data_md directory.
