Dear Christoph
a.) i assume you executed SU53? I assume no result
b.) may be check: DG filling did not happen
I have done a "quick" research and and identified these threads rasing question about "DG filling" I hope that may be some of them help (or at least may be are of interest for you):
DG filling of Density, when a range
Multiple Phrase creation with same description during DG filling
DGE5 (DG Filling from Spec. Management)
EHS: Is there any exit to edit text pattern while filling DG.
How to change the interval real substance for DG-Filling
Can we not display long text as identiifer for hazard inducer ( pure substance )
User-Defined Text Key 1 in dangerous goods
Can you check your "SP" Status for EHS module in your SAP system?
Proposal: try to fill one material; use the debugger; try to identify why you get message "filing done successfully" but nothingis there.
C.B.
