Customers are using CDC 11.4 to replicate tables between DB2 11.5 LUW.
When altering column definition on these replication tables, they hope to minimize replication downtime between source and target DB.
However, CDC only supports DDL replication by rule-based (rule set) mapping with so many limitations.
Requirement 1: Need rule-based mapping support for DB2 range partitioned table.
Requirement 2: Need rule-based mapping support for changing or overriding column mapping encoding.

As discussed in case TS018108676, range partitioned tables in rule based mappings are supported. However, a bug related to a specific test scenario was identified. We will fix that bug. Since the issue is at this heart a bug and not a general enhancement request as requested here, we will close this enhancement request. Please use the open support ticket for any necessary further communications on the issue.
A reminder about the questions above.
The team would also like to know:
Can you please share what has been tested and not proven to work? (This detail is not in the support case)
As an example of the detail we need, is it drop + alter column, add partition, drop partition support when the mapped table is range partititioned AND there are differences in the character set encoding between source and target datatbases?
Thanks for filing this requirement.
For clarity, can you please provide sample table create statements and sample DDL statements that need to be replicated in rules based subscription mappings:
Requirement 1: Need rule-based mapping support for DB2 range partitioned table.
Requirement 2: Need rule-based mapping support for changing or overriding column mapping encoding.
