Hello Veerappa Kammar,
- There is not a by design REST Api in MIM. If you need one please, look on this resourcemanagement-webservice . But it's not a best practice to do that. I would like to recommend to user MIM Sync engine to interface MIM Service and SAP.
- The MIM Sync engine can do a Full import from SAP. The engine is able to do the delta between SAP and MIM, to import only the changes.
- If you interface SAP with MIM Sync engine, the engine will try to apply failure updates at every export (until the export is successful)
- You will have counters (add,update,rename,delete) and logs on the sync engine console.
- Not sure to fully understand this point. You can do both as you can code your own cnnector/MA in MIM.
Best Regards,
Sylvain
