How to grant UPDATE to DBC on DBC.IDCol Tables? - response (1) by M.Saeed Khurram

Kawish,
Can you please explain what do you want to achieve, as discussed in the post you mentioned, you can either recycle the Identity, Or you can use START WITH, INCREMENT BY, MINMUM VALUE,  options in the identity.
I beleive the DBC.ColID can not be updated manually. But you can change the range in DBS, using IDCOLBATCHSIZE, valid range is 1-1000000
