I completed my 5 day SAP ADM100 training course. I can't say that I was impressed. The instructor was nice enough, clear and helpful, and knew what she was talking about, but the course she had to present was not as good.
The more I use SAP, the more I realise it's an awful hack, held together with string and sticky-tape. However it's nice experience to have on a CV, and in the current labour market that's important.
