Business Partner -Replication from CRM to R/3 Errors

Hi all

I am trying to replicate the customers from CRM to R3 and have complete all required settings but still I am not able to see the customers created in R/3...

If I open up SMW01, for some customers the light is green but if i loook in the log it says, no classification maintained for business partner 'ZXYZ' and in some cases the lightis red and it says maintain required fields...

Could you please advise as to how to check on R/3 side (similar to SMW01 in CRM)...I tried looking at SMQ1 and SMQ2 and strangly both there are no entries at all in them 😔

Thanks much

Jai
