Indication of the reason for conversion by drop/create

In our environment, we try to execute all changes to DB2 tables online via Alter commands if possible. However, there are a lot of reasons why in some cases the Alter is not possible and as a consequence Admintool correctly chooses the conversion via Unload/Drop/Create Load/. However, in our environment these are often unintentional small things, which are sometimes also easy to correct. (e.g. new column not null must get a default, the new column is accidentally not added at the end etc.).
Therefore it would be very helpful for us if AdminTool always writes out the reason for the change via drop/create in a message. Then the executing DBA can evaluate the reason and decide whether a change of the input DDL or database model is possible or whether the WSL is executed as it is. 
Often the reason is obvious, but often it is also - especially for inexperienced DBAs - difficult to find out the cause.

    This will be implemented in a phased approach.

    Phase I is complete and is delivered via APAR PH61897

    This phase covers:

    • Inserting a column into the middle of a table

    • Appending a column without default
