Last updated on MAY 09, 2017

Applies to:

Oracle Warehouse Builder - Version to [Release 11.2]
Information in this document applies to any platform.


Oracle Warehouse Builder 10gR2 has been migrated to Warehouse Builder
The deployment of some mappings fails at validation step with following error :

RTC-5325: The generator was unable to produce any valid objects, please correct the source object(s) before trying to deploy again.

The deployment log shows :

VLD-1800 illegal use of sequence operator ["MY_SEQ"] in a complex mapping.
Sequence operator ["MY_SEQ"] are used in a complex mapping which requires generation using a nested subquery (typically a map with aggregation or order by, or complex operations followed by a join). Sequences are not allowed to be used in nested subqueries. Please reorganize the map.
Hint: move the sequence operator as close to the target as possible

Looking at the mapping, the sequence Operator is directly connected to the target table.
