to get a clear view you need to know that indian caste categorization is different from reservation . Reddy means last name given to rulers , all reddy subcastes used to be heads of areas , they have kapu in their caste original name like  panta kapu , velanati kapu, Pakanati kapu , palle kapu etc. Basing on their area of origin pakanadu velanadu etc some being land lord like panta which means crop and palle is derived from being village heads and landlords , reservation system is based on socio economic status at the time of British rule as per their analysis which is nowhere related to Indian caste system so why Velamas stay in different categories . For Reddys only they have fallen under OBC . Checking any existing record of reddy subcastes you will have palle subcaste in it

Hello, caste is a state specific subject meaning a state can declare a caste as forward while other state can declare the same as backward category. Kindly specify the origin state so that we can provide you with that state list of categories. Here is the list of centrally recognized backward classes based on the state, the state may have additional categories added on its own http://www.ncbc.nic.in/user_panel/centralliststateview.aspx

Hope this helps.
