Hi Venkat
Is your concern of problem that you are getting new skill and more money but the money is not the average of the industry for that skill? Remember, average will consider those you are freshers through to the 10+ year experienced experts. If you are new to the area, it sounds like it would be reasonable for you to earn less than the average.
In terms of types of work - project based implementations and support - if you were to have a search of the careers space you will see a lot of freshers and others say how difficult it is to get an opportunity in those areas
You have mentioned that you are doing ABAP currently but have not mentioned how many years. Years in the job will have a correlation with pay rates. I'm also assuming here that if you are not a fresher you may have less than 5 years experience. Apologies if I'm wrong.
You have also mentioned this is a reputable company to work for. Based on your summary you are getting new skills and training and reputable company which benefit your job opportunities, possibly job security as that company will have work for you and make your resume move to the top of the pile. Additionally, the reputable company will most likely enable you to continue to learn the new products and continue to diversify. The trade off for this appears to be the money.
My motto with work is to always chase the skill set and reputation. Chasing money alone is a risk as you lose track of the market and may find yourself with redundant skills. Long term, the skills and experience will pay off.
Good luck with making your decision and your future work opportunities.
