TR2317
The level level_name is designated as unique. Source value source_value was used
in an attempt to create a category in the path drill_path_1. source_value already
exists in level level_name in the path drill_path_2.
This error indicates that you have a problem related to level uniqueness. This can
occur when
v you disable some error-checking options so that Cognos Transformer no longer
v you use multiple data sources in a model and do not define levels associated
v you create an alternate drill-down structure that requires a unique convergence
v you specify that a level is unique and Cognos Transformer detects that it is not
v there is some other problem with the source data
Procedure
To resolve the problem, examine your source file and ensure that the data is valid
for your model.
TR2318
Cognos Transformer has detected n attempts to create a category in more than one
path. Refer to the online help for a detailed explanation of level uniqueness.
This error indicates that you have a problem related to level uniqueness. This can
occur when
v you disable some error-checking options so that Cognos Transformer no longer
v you use multiple data sources in a model and do not define levels associated
v you create an alternate drill-down structure that requires a unique convergence
v you specify that a level is unique and Cognos Transformer detects that it is not
v there is some other problem with the source data
Procedure
To resolve the problem, examine your source file and ensure that the data is valid
for your model.
TR2319
A convergence level in an alternate drill-down path must be unique.
This error indicates that you have a problem related to level uniqueness. This can
occur when
v you disable some error-checking options so that Cognos Transformer no longer
