SMQ2 entries - PI dummy activities cannot have input/output nodes

Hi

I've just completed an upgrade of APO from 30A to SCM5 SR2.

I'm trying to reconcile differencies between R/3 and SCM with the DELTAREPORT3 (/sapapo/ccr).

It keeps coming back with alot of entries for Planned Orders.

When I try and reconcile (send to APO) the APO inbound queue (SMQ2) fills up with loads of SYSFAIL entries.

Each entry has the same error "PI dummy activities cannot have input/output nodes".

Can anyone shed some light on why this could happen, and what this BASIS guy can do to resolve?

thanks,

Stephen
