Hi guys,

Does anyone have any good material / suggestions on the following points concerning XI and it's ability to support an ESA:

1) BPM/BPEL modelling

2) integration with adapaters and routings

3) integration for business activity monitoring

4) creating adapters to nonSAP

5) security considerations

6) master data consistency

7) integration with WebDynpro, BiW and Portal

Regards,

Dan.
