The ProcessingKeyErrorLogFileName property of MDStore interface stores a directory path to a file for logging dimension key errors encountered during processing.
String
Read/write
Dimension key errors occurring during processing will result in a row being appended to the error log file if specified in this property. This file is in comma-separated values format (.csv) with the following fields:
A key value that fails during processing may be written more than once. Thus, it is possible for this value to fail multiple times during an operation.
This error log file can be used to find rows in the fact table that do not correspond to rows in the dimension source table. For example, you can import the log file into a table within Microsoft® SQL Server™ 2000 and construct a query with an inner join between the fact table to the error log table to find the distinct rows that will not match.
By default, this property applies to the entire cube. However, it can be overridden by the value for this property for the individual partitions of the cube.
