Procces Chain problem

Hi all

We are using NW2004s (BI & EP) for our company management reports.

Daily morning BI-Team will run process chain for the actual business

report as of latest status. Some time this process chain get failures

due to some wrong datas.

In failure situations of process chain ,BI-team re-scheduling the

process chain in working hours around 8am in the morning and it takes

3hrs to complete , due to running of process chain all work proces

(DIALOG & BACKGROUND) are fully occupied. So end user canu2019t able to

access and view the report they are waiting for execution.

Please guide us how to overcome from this issue.
