RE: Fixed Asset error - G/L integration must be equal to "Yes" in Depreciation Book Code="Company". Current value is "No"
Josh,
You setup the Depreciation Book, for your Fixed Asset Depreciation calculation, with G/L Integration - Acq. Cost = FALSE and, I am guessing, you are on a Purchase Invoice trying to post the Acquisition of a Fixed Asset or you are on a Fixed Asset G/L Journal trying to post the Acquisition. When using a Purchase Invoice and the FA G/L Journal the G/L Integration, for Acquisition Cost, MUST = TRUE. Go to your Depreciation Book, for the Company, and set the G/L Integration - Acq. Cost = TRUE.

Note that there are other G/L Integrations options and normally when you are LIVE, you do setup the Acquisition Cost, Depreciation, Write-Down, Appreciation, Disposal, and Maintenance (if utilizing). This way the Fixed Asset Sub-Ledger is always in-sync with the General Ledger accounts associated with Fixed Assets.
Hope this helps.
