Should Inv. =Amount Rounding Precision for Local Currency

I got a little problem while changing Inv. Rounding Precision of local currency
from 1 to 0.001 (I think all you have configured this well in the first setup).
After I traced, I found that it should be same with Amount Rounding Precision.
But I also can't change Amount Rounding too, I found that I have to delete posted General
Journal. Then I meant to Compress it using Date Compression > General Ledger.
But I also can't easily compress since its dimension is used in Analysis View.
After I retain all used dimension, I process it, and get other problem...
System display that "Date Locked must be Yes in Accounting Period Starting Date='01/01/02'"
I think I have had very troublesome steps on these.. ](*,)
Anyone could advise me, Am I wrong or correct, then what should I do furthermore on these?

Thank you in advance as always.
