Dear Jonas
only an idea: can you try to prepare the same data situation in dev or qual system and then e.g. change density and do refill. I would like to knwo if such a general change would trigger the refill of any material (any DG master related to the materials) assigned to REAL_SUB.
Which SAP Version you are using? Did you activate business functions in the area of DG? Did the effect occur only with this special REAL_SUB and on a different one having attached working and non working materials the refill does have an effect regarding all materials?
What effect happen if you exchange the DG_CL_SUB and the reexecute filling? may be you have one DG_CL_SUB in place with the "old" situation (not added the new regulations) or you have a different one.
Normally there is a DG_CL_SUB in place defining "no dangerous goods according to transport regulations"; What happens to the DG master if you assign this one (the three new regulaitons should be available on DGL_CUB_SUB level)
