=SMALL(IF(LEFT([Mappe1.xlsx]Tabelle1!$B$1:$B$100,3)="A1C",ROW($1:$100)),ROW(A1 ))
ans copy down

better:
=IF(ROWS($1:1)COUNTIF([Mappe1.xlsx]Tabelle1!$B$1:$B$100,"A1C*"),"no match",SMALL(IF(LEFT([Mappe1.xlsx]Tabelle1!$B$1:$B$100,3)="A1C",ROW($1:$100)),ROW(A1 )))
and enter the array formula with CTRL+Shift+ Enter
and copy down.
