Hello, Yehia and thank you.   Since I am not an ERP project manager and don't know your background, I am the wrong person to do this for you.  However, this is how you do it for yourself:  1. Find a job description from a major corporation for an ERP project manager.  Find a few, if you can.  Step 2: On a piece of paper, bullet point out their requirements on the left column.  About 6-8 skills and experiences they are asking for.  Step 3:  On the right side, match your skills and experiences with each bullet point or write GAP if you need to go get some new skills.   There!  You have your comparison sheet AND specific examples as to why you are the best ERP project manager!
Best of luck, 
Dana
