Re: Do we always need a middleware to integrate CRM System with an ERP system ?

Hi,

We do not need a middleware to integrate between CRM and ERP system.

The below following methods can be used to import/export data between the two systems.

1. Standard Batch / Direct Input
2. Batch Input Recording  
3. BAPI
4. IDOC.

See the below link to get a better idea for the same.

Hope this is useful.
