Clarification on use of certain Fixed Assets AAIs

Hi All,

I seek some clarification on usage of certain fixed asset AAIs.  Could you please clarify why the following are used?

1) F01-F28?

2) FX07/08? Are these it used for Location billing or for some other purpose too? Do I need to populate these with my disposal accounts (WDV, Proceeds, Cash Clearing)?

3) FX10-FX11? Are these used only if equipment module is being used? What if equipment module is not being used? Shall I let the default values sit there?

FX10- 8115.EQPT

FX11- 8115.EQPT

4) FX13,FX14: My understanding is that these should cover all the three disposal accounts - WDV, Proceeds, Cash Clearing. Pls confirm.
