Hi Thomas!
Sorry, but have to revisit this thread and correct my reply. I thought it works, but found out, that was wrong.
I will later attach screenshots of my customizing and test results. Maybe you can check at your side the same?
P.S. Hope you will be able to realize manual sorting of mappings in the future. And (if you include this in your development plan) than it would be clever to provide such control not only for structure mapping (/AIF/T_INTREC), but also for field mapping level (/AIF/T_FMAP). In later case, maybe this can be also sorted out by using separate structure mapping numbers (SMAPNR). Still direct ability to set sort direction would come handy.
Best regards,
Petr Perstnev
