I'm not sure if I should stick to SAP GRC & SAP implementations or go in for ISACA certifications since several years. Which certification will you suggest for each of the following if one has experience in:

1) SAP Risks and Controls associated with business processes and functionality (Financial Record2Report, Procure2Pay, Order2Cash)

2) SAP SoD (Modules:Financials, Material Mgmt. & Sales & Distribution modules; Processes:R2R, P2P, O2C)

3) SAP Auditing (as in preparing audit plans, audit programs, ICQ's, Test scripts/plans/ steps) of Business cycles (Expenditure, Revenue, Inventory and Basis/Infrastructure)

4) Also can someone tell me which ISACA certifications CISA, CRISC, CISM & CGEIT are closely related/suitable/relevant to which of the following SAP GRC modules/areas (SAP GRC-Access Control, SAP GRC-Process Controls, SAP GRC- Risk Management & SAP Security).
