SAP GRC OR CISA/CRISC/CISM certifications ?

in CISM
Which of the two is desirable - investing (time and money) in SAP GRC & Auditing OR CISA/CRISC/CISM certifications in case the person has experience in SAP Proj Mgmt. (implementations) as well as SAP GRC/Audit projects.
I'd like to hear especially from those who have worked in ERP implementation (SAP, Oracle etc) as well as SAP GRC/Audit areas and also have ISACA certification.

So, this greatly depends on what you are currently doing, what you want to move into and where you want to go long term. If your goal is SAP Security Admin/analyst/manager, then GRC 10.1 cert is the way to go. That said, if you want to move more into an audit related role, where you will touch on multiple modules of SAP, then CISA is the way to go. I know that at my company, they have a hard time finding SAP security folks who do not have very specific and particular experience in one module of SAP. Since it sounds like you have already worked in a consulting capacity and have experience with SAP, then going the direction of CISA could be valuable as it would position you to move into IA. This would provide more opportunities to assist on Business process related work.
