Hi Gopal,
Yes you are right it is for Basis team. We have recently implemented SOLMAN ChaRM but I never see guys who implemented by functional or technical ABAP... All those guys are from Basis and business release management / change management team. You have to always keep wider option in SOLMAN because I have done a certification in SOLMAN ASAP Methodologies and I am a functional guy. Moreover, I never worked on SOLMAN to configure for upgrade or implementation or rollout projects, so only big companies they need a separate a person to have in SOLMAN ChaRM in SAP world. However, current trend is changed all over the world. The guy should have minimum of two modules or two systems to be known. So, when you try for SAP opportunity just have your ABAP Business workflow as well.
