Replicating customer from R/3 to CRM found Acct group y001 do not exist

Hi gurus,

I tried to replicate the customer master data from R/3 to CRM. Using Tcode SMW01 i found out that Account group Y001 do no exist.

Note:

Y001 is the account group i created in R/3. I also assigned it to CRM grouping Y0 using tcode PIDE.

Kindly help regarding it.

Regards,
