Data is not coming for a month after Consolidation

Hi,

Our System details are SAP BPC 10.0 SP7 NW. EPM Add-in SP18. BW 7.3.,

We have a strange Problem. When we run the Consolidation, Data is not populating for a OCTOBER month with the GROUP scope. But when run the Consolidation for NOSCOPE, data was populated for all months. Checked all - Business Rules, Script Logic.... Everything seems OK. The same Consolidation was worked fine till Monday. We are facing this issue from Wednesday onwards.

Request you to guide me in two things:

1. How to Debug the Consolidation Package.

2. What would the reason for this and how to find it.

Am i missing anything to check. Any SAP note available for this type of Problem.

Thanks,

Sekhar.
