I have ERP 6.0 (ECC 6.0) with IS-OIL pre-installed however I can't see it in SFW5 or SPRO. Is it de-activated if so how do we activate it?
Also I can't find any Installation Manual of IS-OIL under SAP ERP and I guess it is because its built-in.
It is because in your system another IS Extn is already active and you can have only 1 IS extn active at a time. Also this is a irr-revocable process. Once the IS Extn has been made active, you can't really go back and de-activate/activate another one.
