Business Central enforces that "FA Posting Type = Acquisition Cost" must be posted through the FA Journal, not the FA G/L Journal, when:
The Depreciation Book used is not integrated with the G/L (i.e., Integration → G/L = No on the Depreciation Book Card).
OR
The posting setup is designed to separate FA Ledger entries from G/L for Acquisitions, which is typically handled by the FA Journal.
This behavior is by design, not a bug.

✅ Solution:
Check the Depreciation Book you're using:
1. Go to Depreciation Book (Search it).
2. Open the Depreciation Book you're using (e.g., COMPANY).
3. Make sure that "Integration → G/L" = Yes if you're planning to post through FA G/L Journal.
4. If "Integration → G/L" = No, then you must use FA Journal for Acquisition Cost entries.
So:
✔ Use FA G/L Journal only when Integration to G/L = Yes
✔ Use FA Journal when Integration to G/L = No
