SAP SNC APO Integration

Experts,

We are planning to send demand and inventory data from APO SNP to SNC system for SMI Scenario.

I would like to know what settings/activation needs to be done in in APO and SNC

As far as I know 9ASNP06 is used as planning area and /SAPAPO/PROACT_OUT  t-code to transfer the demand and inventory data.

1. Any other Settings in APO

2. Settings in SNC 

3. For demand and inventory transfer which key figures to select?

Thanks,

RB
