When I run a mapping task, the task fails with the following message:
TE_7073: Expecting Keys to be ascending.
This occurs when you configure an Aggregator transformation for sorted data, but do not sort the data earlier in the data flow. For some connection types, you can configure a Source transformation to sort data. You can also use a Sorter transformation.
When I run a mapping task, the task completes successfully with the following row error message:
FR_3016 Row [<row>]: Record length [<row length in bytes>] is longer than line sequential buffer length [<maximum buffer length in bytes>] for [<file name>]. Record will be rejected.
This message appears when the number of bytes the task reads for the row exceeds the calculated maximum line sequential buffer length.
For example, if the code page of the source flat file and the code page defined for the connection don't match, the row length can exceed the calculated maximum line sequential buffer length, and Data Integration rejects the row.
To resolve the error, configure the Line Sequential Buffer Length advanced session property and set the value to the record length in the error message.
