Deleting Assets in POA from AP or PA

Hi ,

1) Can we delete an asset which has come from AP or PA in POA?

2) Also what are the conditions in which an asset can be deleted in POA like can delete be possible in the following scenarios

a) Add an asset ( backdated or not ) - No create accounting or NO Deprn

b) Add an asset - accounted in draft, no deprn

c) Add an asset - accounting in final , deprn run

d) Add an asset , do a transaction on it and then either run/do not run CA or Deprn

In the UG , it simply says that we can delete an asset as long as it is in POA, does not mention about the conditions
