Hello Cathy
The Target Alias in detail 1 band and detail 2 band or OK !
Detail 1: "legende"
Detail 2: "listwahl"
But i found a solution:
The detail 1 records had a print when condition from cursor listwahl!????
if listwahl.showlegend = 1
In all records from listwahl showlegend was 1
I put the showlegend column into cursor legende and changed the print when to
if legende.showlegend = 1
Now everything works as expected!
Nevertheless:
Thank you for your efforts

Best regards
Albert
