Impact on BI after ECC 6.0 Upgrade from Ehp 3 to Ehp 4

Hi All,

We are planning for an upgrade of our ECC 6.0 System from Ehp 3 to Ehp 4.

Could you please provide me inputs in what needs to considered in terms of BI system?

I know the following thing:

1) Delta Queues must be cleared before the upgrade starts but what needs to be considered for FI and CO Data Sources.

Any SAP Documentation available?

Thanks,

Neelesh
