Upgrade from ECC5.0 to EHP4 with no SAP_APPL
I am having a ECC5 with e-recruitment 600 on a stand alone system. Now we like to upgrade to E-Recruitment EHP4. I dont have SAP_APPL component. does SAP_APPL require for E-Recruitment upgrade?
My functional consultent says it doesn't require for E-Recruitment.
