Dear Dinesh
Pl ensure whether data is maintained @ SAP_EHS_1023_057 in compound level & Composition parameters @ SAP_EHS_1012_003 substance level.
if not maintained & again execute RREGCH_FILL & see the log whether data is transferred or not , if transferred and raise the PO and then Run the programme RREGCH_VT and check the log . In that log Under you scenario if the records are appeared in planned qty , then you can check RREGCH_VM . If records are not appeared & appeared in "Entries to be deleted" .. this is again a technical issue which is not working in the configurations lower than 606 ,sp07
