I often hear the comment that Dynamics NAV posts too many Inventory Sub-Ledger entries to the General Ledger.
There is a way in Dynamics NAV to reduce the number of General Ledger entries when running the batch report “Post Inventory Cost to G/L”. When running the batch report, select “Per Posting Group” and the system will summarize the inventory transaction Value entries by Posting Group and make substantially fewer General Ledger Entries.
