Excel export not working .. missing file xx..sc_free_total.class.php

Hello,
in my grid i have a normal excel export button. It’s not working. I get the error message :slight_smile:
Fatal error: Uncaught Error: Failed opening required ‘D:/SCV9_9/wwwroot/scriptcase/app/SVSB/sc_schueler_list/sc_schueler_list_resumo_sc_free_total.class.php’ (include_path=’.;C:\php\pear’) in D:\SCV9_9\wwwroot\scriptcase\app\SVSB\sc_schueler_list\sc_schueler_list.php:2986 Stack trace: #0 D:\SCV9_9\wwwroot\scriptcase\app\SVSB\sc_schueler_list\sc_schueler_list.php(5158): sc_schueler_list_apl->controle() #1 {main} thrown in D:\SCV9_9\wwwroot\scriptcase\app\SVSB\sc_schueler_list\sc_schueler_list.php on line 2986

And really the file sc_schueler_list_resumo_sc_free_total.class.php is not in the folder, so SC did not generate this file ??

Thx Uwe
