What does a posting book do?
Posting books transfer journal entries to a general ledger. To do this, posting books take depreciation expense and accumulated depreciation amounts calculated for a book and post this information into journal entries for the general ledger.
Only one posting book is allowed for a company. After a book and calendar are designated as posting and any asset processing has occurred, the posting designation cannot be changed.
Posting books are required if you plan to generate and post journal entries to the Lawson General Ledger application or to a non-Lawson general ledger.
