Use the following rules and guidelines when you configure SAS mappings:
You cannot configure the Update Strategy transformation in a PowerExchange for SAS mapping. Alternatively, you can use the Load Type writer capability to model the update strategy.
You cannot configure a Lookup transformation in a PowerExchange for SAS mapping.
You cannot read data from a SAS file that is created with data compression (COMPRESS=CHAR or COMPRESS=Binary).
When you read data from a SAS file, the page size of the file must not exceed 65536.
