Reg: Replication of sales documents from CRM to R/3

Hi

When we are trying to replicate sales document from CRM to R/3 everything is working fine except posting of document into r/3. BDOC is getting generated with green status, If we see the error log for BDOC it is showing message that r/3 adopter is called but document is not posted to the r/3.

Whts the reason for this...??Can any middleeware guys me help in this..?
