Assalamu Alaikum,
Could you please tell me where you are taking the classes for SAP-HR, because am also taking classes and am at initial stage so, will you please tell me that, if one should get a job in SAP-HR what are the criteria s for that, and I am doing four sub modules, OM,PA,TM & Pay roll, and i've done with OM and now I am in PA, and i have a question for you that, only practical Knowledge is sufficient to get a job or else anything more...
Please let me know
ALLAH HAFIZ..

We have to purchase SAP HR and I thinks its cost is aroung 1-2 lacs and maintenance cost per year is high, but i dont have any idea, if some one share how much we have to invest in the software and maintenance cost than it will be useful.
For SAP Courses there are many private institution who provides such courses but if we dont have SAP in our organisation than it is not useful to do course, b coz if we not do practical we will forgot what we have learn in the course after 6-12 months.
