Extract data from IDES ERP

Dear Expert,

Good afternoon.

I have BW development system.

In order to test extracting data from ERP, I want to use IDES (ERP).

Then I have some question about IDES.

Q1. Can I register IDES as source system at BW system?

I have a concern that I can't connect IDES to BW.

Q2. Can I customize for data extraction at IDES? (ex. t-code RSA5, RSA6, RSA3 etc...)

Q3. Can I create generic data source at IDES?

If there are restriction using IDES for BW verification, please let me know.

Best regards,

Taka
