Webi report is failing while refreshing with no memory error but works without issue when refreshing

[PriyankBhayani]

Hello All,

I am facing strange issue that when i schedule one SAP BusinessObjects - Web Intelligence (WebI) report it runs for around 1 hour and then fails with memory error in backend BW (SAP Business Warehouse) system. while checking in BW i can see the memory dump

Now surprising part is if run the same report manually in web intelligence with similar parameter it runs without any issue and generates the output in about 10-11 minutes. 

Here i fail to understand why it is behavious in this way.

Anyone have faced such issue and know the possible root cause?

Additional Information:

SAP BusinessObjects BI Platform 4.3 Support Pack 4 Patch 6

Version : 14.3.4.5014.6

Scheduling output is CSV Archive
