Which is more successful in the MENA region, Oracle ERP or SAP ERP offerings?

SAP is way better than Oracle ERP, when I first tested it by the year using its SAP Business One version, you will be at ease since it can generate report, set meetings, monitoring the production line, generate HR Reports, Financial Statements and a lot more for a single business entity. Now that it has the SAP ERP you have the capability to manage the business properly when it comes to manufacturing, HR Process, Accounting Records, one thing about SAP that I like the most is its convenience when you are exporting files to MS Excel, there's no hassle in sanitizing the data that you want. Another thing is that it uses "universal" functions, wherein you can use the same codes in a different company as long as they have the same version, it does not complicate things. :)

Oracle has succeeded in its work and SAP succeeded in  its work, but if we talk about the Middle East, we find that the problem in the culture of the companies  , end users

And business owner 

  companies  size  as well as the maturity of these companies in the containment of ERP Systems 

   Which is crowned with success or failure of work may succeed SAP might succeed Oracle but ORACLE OR SAP  will not be the cause of success or failure for the  ERP but succeed RETURNED TO

 the maturity of the organization to accommodate the technological and the presence of structural and regulatory accounting good is the most important factor for

succeed 

companies that are using Oracle are swiching to SAP. 

Sure, SAP is leading in MENA

SAP is mostly used in MENA regions. But security wise ORACLE is the best.

I don't know of deliberat accurat measures but I beleive that SAP have a higher share of the  international ERP market in the region.
