Create Dynamic Partition

This Subflow is only used in Change Only Mode. It detects the smallest partition surrounding the extent of the change (job extent) in the target dataset. It then identifies the equivalent partition in the source data.

Subflow steps:

1. Build Topology

   Topology needs to be built on the partitioning features to perform the partitioning.

2. Create Dynamic Partition

   This step detects the smallest partition surrounding the extent of the change (job extent) in the target dataset.

3. Create COU Source Partition

   This step identifies in the source the partition which is equivalent to the target that had been computed in the previous step.

4. Delete Old Partitioning Features

   Deletes all the target features which are used to form partitions. These had been loaded to compute the target partition, but are no longer needed. They are deleted to ensure they do not interfere with newly generalised features inside the COU partition.
