Hello,
We are considering other options with SAP-OER & SAP-AII, more specifically SAP-OER without SAP-AII. As I understand there are two versions of AII. One AII resides inside OER and one or more optional external or stand-alone AIIs. My line of inquire is; if you just want to post an event through EPCIS to OER, do you need any AIIs at all (internal or external.)
It seems originally AII served a line interface. It also has extensions to talk to devices. But if you already have line managers why would you have one manager talk to another just to post the event?
Now the question becomes; what are the specific functions of the internal AII. I realize there are other reason to have external AIIs; such as redundancy for WAN communications, but those issue can be address in other ways.
Internal AII appears to be the brains of the AII operation (passing SNs) while the external AII acts as the arms and legs dealing with the outside world (pushing out and receiving back SNs and translations of formats.)
Comments?
