The problem concerns missing messages in the PWP logs during ILM-related operations:
In version 12.3.9 the logs were showing this type of messages

Whereas in version 21 the PWP logs contained the following for the same ILM operations.

1. The U#5344 message no longer contains the number of the checked beforehand, it is replaced by a special character.
2. The simulation messages are listed but the "ILM: ALTER TABLE ......" instructions are no longer present!!
Automation Engine 21
This is a defect of the Automation Engine up to the fixing version.
Bug Description:
When checking partitions, we have noticed that the partition number is being displayed incorrectly. Additionally, we have observed that when executing SQL commands, specifically the "Change_partition" operation, the corresponding actions are not being logged in our system logs.
This bug is fixed in the following versions of the Automation Engine
21.0.8 HF5
21.0.9
Bug ID: AE-33079
Bug Ticket: ILM - missing/abormal information in the logs after 21.0.7 Upgrade
