Actualize load plan or freight order cluster in multicompany environments

When a load plan is actualized, the loads and shipments are updated in the Planned Loads/Shipments (whinh4180m000) session in Warehousing. Warehousing can use the planned loads and shipments to plan warehouse activities. Freight must update the planned load and shipment data in the originating company of the freight order lines that belong to the shipment lines in the loads and shipments stored in Freight. A single load can contain freight order lines from multiple originating companies. For multicompany warehouse transfers, the planned load and shipment data in the Planned Loads/Shipments (whinh4180m000) session in both the originating company and the related company are updated. This process is similar to freight order clustering.
