Different GI / GR Document number while making the COR6N

Hi All,

We are using the automatic GI/GR for one of our plant first time through COR6N transaction code..

both GI and GR is happening along with confirmation. But the problem is that system is capturing the one document number for both GI and GR..

as per the requirement system should capture the different number range for GI and different number range for GR

if make manually GI and GR through MIGO system is capturing the different because we have assigned WA document type for GI and WE document type for GR in OMBA

for automatic thing how to maintain two different number ranges for COR6N..

could you please help some one to get this done

Regards,

Venkatesh
