Asset Accounting : Load Asset Balances

Hi,

We had an issue relating to asset balance upload:

We have Asset transfer date: 06/30/2007

While loading asset values for asset having capitalisation date before 12/31/2006 system is accepting the values for accum book value in AS91 ( field is ready for input) but for asset with capiatlisation date after 12/31/2007 say 03/01/2007 system is not accepting accum book value ( field is not coming as input enabled its greyed). Need to confirm how the balances before 06/30/2007 should be loaded for assets having capitalisation date on or after 01/01/2007.

2. How GL Balances will be tallied for these assets? Any program to load GL values.

Your early response to this will be highly appreciated..

Regards,

Vipin
