Hello SCN world,
I'm working on interfaces. Sending from SAP ECC, to an external system, through PI.
I have to send Vendor master data to the Partner, through PI.
I have Abap, SAP basis knowledge, but zero knowledge on PI 
.
So the interface will be in 2 parts mainly:
1) SAP ECC ==> PI (idocs)
2) PI ==> Legacy system of Partner (flat file, xml file,..) .
My idea is so:
For 1): Sending idocs of type CREAMS from SAP ECC6 to PI. Using standard Tools to do it, in collected idocs mode.
For 2): Once PI receive the idocs, send XML file to Partner.
I assume that connections pre-requsites are all OK (ECC => PI ; PI ==> LS)
For 2):
I have no really idea of tasks to do. I assume that there are integration, mapping & routing tasks to do..
==> If i want to do it the simplier possible (PI received idoc, convert to XML/flat file, send it to Partner).
Could some experts tell me if this is possible ?
And if yes, the main steps in PÏ side to do it ? (I think i'm OK for SAP sending side ).
My concern is the amount of work we could have to do on PI side (receving idocs, mapping, routing, other suprises,...)
Thx all for your help.
SAP Newbie.
