Repeating the Initial Data Transfer
A complete initial data transfer from the R/3 backend to the CRM database can be repeated without restrictions.
On the other hand, a complete data transfer from the CRM database to the consolidated database (CDB) can only be repeated if you have not yet created any
subscriptions.If subscriptions have already been created, the complete data transfer from CRM to CDB cannot be repeated. This is to avoid inconsistencies between the CDB and the mobile application database.
