I was today years old when I found out that this warning message:

Only appears when the table you insert the data from (Y) is lower in the Data Area table list than the table the data is inserted to (X). So this warning only applies when the data area or parts of it are executed without Managed Execution enabled, which is almost never the case.
This warning has caused quite a lot of confusion at some customers, thinking they had to split tables into two because of this warning.
So, the idea is quite simple, please change the warning text to something like:
“When executed without Managed Execution, the table X is executed before the table Y.” Or similar.
