hi
as my personal experience instead of Studying MBA ,you should focus on Subject then you will get more subject,because already your working on sap B1 ,search on Big company may by GOD Grace you get good opportunity..
companys are seeking only subject persons (means experience)
as per your concern your want study Through Distance (MBA) it will take Three years( as per course ) ,we don't know for complete (may be if you done good hard work you may get good score and you will complete with in 3years )
