The reason why you can't combine SELECTINPUT and COPYMOVEINPUT is simple! Both statements will fill the variables (%SELECTION% and %TOSELECTION%) with strings like:
/SIMDEV/INFILE/PrivatePublications/v.kalinin/TempFiles/FROM.TMP@@@SAVE@@@@@@EXPAND@@@|DIMENSION:INACCT|2020202020704|
You can append some dimensions with members to this string, but you can't combine 2 strings like this.
I will correct my sample a bit!
