Drill through to ECC - Licence question

Hej Gurus,

I am consindering doing a drill through from BPC to ECC via a URL, but I have a small questions regarding logging on and licenses.

When a user uses a drill through to open a transaction in ECC, do the user need a logon and licens to ECC, or is this controlled by a BPC user? If all users need a logon and a licens to ECC, then it can become quite expensive to enable drill through from BPC to ECC.

Can somebody tell me the licence rules when creating a drill through to either a Bex query in BW og a transaction in BPC.

Best Regarids,

Mikkel Kristensen
