We are currently working on infrastructure definition for SAP HCM which has to take in consideration our existing landscape SAP FI/CO. Due to the security and SAP platform management reasons, several senarios are evaluated, In some of them, ALE must be installed between SAP HCM and FI/CO and I would like to get a feed-back on ALE installation complexity and on day-to-day maintenance activities. Is that complex to setup and to maintain? SAP Consultants are saying that's straightforward and that ALE can be neglected, trouble wise. Is that correct ?
Thank you in advance for any appropriate feed-back on that topic.
