In credit note, in item data section, there is a tab with Texts.
Those credit notes are created by report/application where you upload file, then hit simulation and release mode button. Those 2 buttons contains a lot of code, but what those buttons do, they fill required tables and create credit note. I went through whole code and found all tables that contains "Notiz".
I deleted those rows, but in the end, when credit note is created, there are still 2 texts with Notiz in item data.
Have you experienced something similar ? Or what are your suggestions ?
