PI Query

[Former Member]

Hi,

I have two basic questions :-

1) If we connect one R/3 system with another through a RFC then also basic communications, say for IDocs takes place. But I have seen at places where even between two R/3 systems for 'IDoc transfer' a XI/PI system is used in between. What is the purpose there ? what functionalities we achieve there by including a XI/PI box in between two R/3 systems for IDoc transfer ? Can anybody please explain this to me ?

For SAP to non-SAP systems or SAP R/3 to http system/file server communication - why XI/PI is used that purpose quite clear to me.

2) I heard PI messages are persisted at IS i.e. at ABAP stack. Now what are tables that contains these messages ? and what are standard jobs that are used in PI systems to archive these messages or delete them ?

Thanks

This wiki has the names of the tables that XI/ PI uses(message storage etc): https://www.sdn.sap.com/irj/scn/wiki?path=/label/xi/pi_tables

hi,

>>>What is the purpose there ? what functionalities we achieve there by including a XI/PI box in between two R/3 systems for IDoc transfer ?

- monitoring in one place

- if there are any mappings you don't need to to them on sap application but in the middleware

>>>and what are standard jobs that are used in PI systems to archive these messages or delete them ?
