Business Partner data migration

Hello all,

we want to migrate Business Partner into a CRM 4.0 System.

For the standard fields we´re using the LSMW. For the Z-Fields we should develop a report for the migration. We´ve enhanced the Business Partners with the EEWB (not only fields, but tables also).

How is it possible to do this? Writing in the z-tables is not enough, because of the replication to the mobile sales. I need to know how to generate BDOCs. Is there a function module for importing BP number and the z-fields and generate automatically the BDOC?

Thanks for replying!
