IS-M Business Partner Migration to SAP Business Partner
Could somebody explain me how is the procedure to migrate business partners when there are master records in ERP?
At this moment, I´m working in an IS-Media implementation, the customer has ERP 6.0 in operation (customer master and vendor master are actived). The Business Partner Migration to SAP Business Partner documentation says: "SAP business partner master records must not already exist in the system when you perform business partner migration.You will also not be able to use the migration tool if you already use the SAP BP in other SAP components. If your system already contains SAP business partner data, the migration reports will terminate with an error message. You must delete this data before you can perform migration. You can do this using report RJGBUPDELE1."
The team project think that deleting data is not the better way because it could be too risky... Do somebody know how to solve this issue?
Thanks in advanced for your help.

the migration tool was created to convert existing business partners from the former IS-M specific business partner management into SAP business partners.
If there are already existing customer master and vendor master records in the system then these records are not changed by the migration tool.
In fact in an ERP6.0 system the migration tool can only be used to quickly setup the customizing assignements between the SAP business partner customizing and the IS-M customizing (e.g. customizing for marital status or form of address).
But this can also be done manually with the corresponding IMG activitites.
If you start with IS-M on an already running ERP system then I recommend the following:
1. Set up the customizing of the SAP business partner
2. Set up the customizing of the business partner in SAP for Media including the assignements mentioned above.
3. Check the assignements with transaction JGZ0
4. Activate the SAP business partner in IS-M using transaction SM30 on view JYVTJY00_SAPBP.
Precondition for this procedure is that there exists no SAP business partner (which can be checked by searching for entries in table BUT000 - there should be no entries).
This precondition is exactly the same as the one mentioned in the documentation quoted by you. But please to not mingle the SAP business partner with customer master or vendor master. They are technically distinct objects.
Btw: you can convert already existing customer masters or vendor masters into SAP business partner using transaction JUCDCM.
