What happens during period end processing?

Period end processing involves closing the Purchase Order period, as well as other Lawson applications. When items are received, running General Ledger Interface (IC130) posts journal entries for the General Ledger (GL) application for inventory and RNI accounts. When items are invoiced, running Invoice Distribution Closing (AP175) creates journal entries for accounting distributions and offsets for the RNI account. Run Received, Not Invoiced Report (PO135) to create auto reversal transactions for non-stock and special items.

Note: Standard cost companies can run Standard Cost Calculation (PO139) to create reversing journal entries for the difference between purchase order cost and standard cost for inventory items.

For more information, see Standard Cost Calculation

To coordinate and time the processing of transactions in the correct accounting period, you may use subsystem close. Subsystem close requires that applications are closed in a particular order:

Note:  General Ledger Interface (IC130) must be run before you close the General Ledger application.
  1. Purchase Order using Subsystem Close (PO199)

  2. Accounts Payable using Vendor Balance Year End (AP199)

    When you run AP199, you establish new vendor group period ending dates for a vendor group and transfer current year vendor balances to last year

  3. Inventory Control using Subsystem Close (IC199)

  4. General Ledger using Period Closing (GL199)
