Dear Rohan
not sure about your explanation. Therefore: in DG you have a lot of "regulations" (e.g. IMDG); now you need to prepare dataa in EHS-BD so that DG filling can work; I believe you need "mapping"; e.g. if you have maintained VAT Dangerous Goods User-Defined Texts with Standard/REG_World teh DG maste rmust get perregulkaiton the same data; but if you have maintained e.g. two data records in the VAT one valid for RID and one for ADR (only an example) you need to differentiate the data instances by usage so that filling is data properly
May be check: DG_CL USER DEFINED TEXT POPULATING THE DG MASTER DURING FILL
