Query on Idoc Packaging with PI7.1 EHP1

Question

HI PI Experts,
I have a scenario where batch run triggers the 100's of Idocs in R3 in few milli seconds, which means all Idocs are triggered in one go From R3.
Do we still need to set Check box for Collect Idocs in Partner Profile in R3 for Idoc Packaging ?
I want to make out the difference in 2 configs for Idoc Packaging where
A)  All Idocs are sent via Report run of RSEOUT00 at a go after collection.
B) All Idocs are triggered at same time via Batch Run at same time.
Assumption:
PI is configured to use Sender Idoc Adapter with Idoc Package Size of 10.
OR
I frame my Query in other way"
What does Collect Idoc and running Report RSEOUT00 achieve to make sure that Multiple IDOC Nodes come into 1 XML message? OR Its only PI Sender Idoc Adpater take care of it when multiple Idocs of same type comes through PI?
Please reply .
Regards,
Anurag

Hi Anurag,
In the sender IDOC adapter if the packaging option is not activated, then the IDoc packages get split into single PI messages, one PI message per IDoc. IDoc sender functionality is enhanced to preserve and process IDoc packages without splitting the IDoc package into individual PI messages. I.e. single PI message contains multiple IDocs including control records. Where as running the report RSEOUT00 will just send all the IDOCs that are in waiting state to their respective destinations.
For the sender IDoc adapter to be able to process packages, it should receive the IDocs in a group. I.e. in the sender partner profile the packaging option has to be activated. Though you've activated the packaging option in the sender partner profile, If you dont check collect option in sendet IDOC adapter then the IDOCs get splitted into individual PI messages.
