Hi Efrat,
I am facing similar issue with org structure.Please advise if report ZCRM_ORGMAN_R3_ORGDATA_DEL helped in removing the org data and regenerate or recopy same sales areas from ECC to CRM.
I was successful first time in coopying the sales area from ECC to CRM.But unable to repat it again for teh same org unites.I have removed all org units from CRM and starting all over again.
Thanks,
Rahul
