Updating Employee record in Mobile bridge

Hello Experts,

I am trying to update the employee record flowing from CRM to CDB. I am using the BADI method USER_EXIT_DOWNLOAD_BP_MAIN for the same. Inside this I am successful in updating the structure of the employee_write. I can see the same in SMW01 with the Z fields containing the correct values. However when I go into the SMOMITABT table I cannot see this data for that employee record.

Any pointers where I could be going wrong?
