I was not a SAP consultant or expert, but was once involved in a SAP implementation for the Belgian railways as a maintenance expert (what I was, I am retired now). I had access to the "sand box" or how was it called, in fact the playground of the "almost" working system.
I was trying to find a solution, for a typical maintenance management problem (allocating costs from a workshop to another cost center or something like that, I don't remember exactly, but it was a bit more complex).
The SAP consultant told me this was impossible, and I thought: "this should be possible".
Playing around I found the solution, and I told him I had "the" solution. He said, "impossible". Didn't want to look.
I called his boss:
- "But Jean this is impossible" (the other guy was also present and had a big grin on his face - we didn't like each other)
- Me to his boss: "You have 5 minutes?"
- He: "yes"
- I did set up the solution, step by step
- He: "waw, didn't know that"
- The other guy walked away
SAP is very powerful, but often not configured as it should be: pressure of deadlines, junior consultants, lack of expertise, ...
