Prateek,
Aha, now I am beginning to understand your frustration. Since you are an MM consultant, it makes perfect sense that you would not be familiar with Transportation Management, as this is not an MM topic at all. TM solutions are not normally managed by MM consultants.
If you wish to expand your non-MM knowledge base, you might want to consider trying one of the many SAP schools that are available. Here is one, which happens to be based in the US. If you are not a resident of the US, I am sure you can also find a similar one closer to your home.
Best Regards & Good Luck,
