Impact of 'Allow GL posting' enable disable in FA Book Controls setup

Hi Experties,

We had implemented the Fixed assets and its running normal with one corporate book and allow GL posting enabled.

now we get the requirement to define new asset book (corporate) for only tracking the assets which should not generate accounting entries

i had defined the new book like as first book. and only change did is 'allow gl posting' un-checked. then created the asset and ran the create accounting. it has generated the accounting entries and able to see the report output and then when i check in GL this entry has not moved. this is we need.
