Hello,
I am building a concept of a remote cube based on a APO source system in BW system
System 1: BW 7.1 system
System 2: APO 7.02 system
Users are expecting a live access of APO data for reporting from BW system. This helps them to have a single system to setup reporting , ie BW system. Still can have some live reports from APO system. APO inturn brings some more information from R/3 via livecache..
APO data source has been generated via TCODE /SAPAPO/SDP_EXTR.
Now want to add some custom fields from APO master data setup. How can we enhance the data source before sending these information to BW.
As you know the Customer Exit based enhancements are NOT supported with Direct Access DTP. 
.. Then what is the way to go?...
Thank you
Happy Tony
