SAP TM 9.5 and Legacy System Integration

Hi Experts,

I am looking for a solution wherein SAP TM 9.5 will interact with Legacy systems (Oracle ERP and Mainframe) for Inbound and Outbound flow of data (both Master Data and Transactional data)

I need your advice on how to integrate Legacy System (Mainframe & Oracle ERP) with SAP TM 9.5

In case there is any case study can be shared, will be grateful.

Regards

Niladri
