Manufacturing: MRP Enhancements

In MYOB Acumatica 2024.1, other improvements to the inventory planning processes have been introduced, as described below.

Excluding Inactive Warehouses from Inventory Planning

In previous versions of MYOB Acumatica, planning suggestions for material requirements planning (MRP) were generated for inactive warehouses if the following criteria were met:
  • The Active check box was cleared on the Warehouses (IN204000) form.
  • All of the check boxes in the Inventory Planning Settings section on the Inventory Planning tab were selected.
This resulted in incorrect inventory planning results being displayed on the Inventory Planning Display (AM400000) form.

In Version 2024.1, when the Active check box is cleared on the Warehouses form, all of the check boxes in the Inventory Planning Settings section on the Inventory Planning tab are cleared and read-only.

Including or Excluding Orders in Inventory Planning by Order Type

MYOB Acumatica 2024.1 introduces the ability for users to exclude or include supply plans by order type on the Order Types (SO201000) form.

The new settings are visible for an order type if the following conditions are met:
  • The Material Requirements Planning feature is enabled on the Enable/Disable Features (CS100000) form.
  • In the Operations column on the Template tab of the Order Types form, a row contains Receipt, indicating that this operation is generated for an order of the type.

The Include Returns in Inventory Planning Supply check box is displayed in the new Inventory Planning Settings section on the General tab of the Order Types form (see the following screenshot).

When the Include Returns in Inventory Planning Supply check box is selected, supply plans by order type are displayed in the list of planned orders on the Inventory Planning Display (AM400000) form. After an upgrade to 2024.1, the Include Returns in Inventory Planning Supply check box on the Order Types form is selected for all order types containing a Receipt operation. We recommend that an administrator review the settings of all order types with a Receipt operation after the upgrade.

Specifying the Planning Horizon for Inventory Planning

In MYOB Acumatica 2024.1, users now can specify the planning horizon value on the Inventory Planning Preferences (AM100000) form. With the planning horizon specified, during the regeneration of inventory planning on the Regenerate Inventory Planning (AM505000) form, the system will process only item plans with a supply or demand date that is earlier than or the same as the regeneration date plus the number of days specified in the Planning Horizon box (see Item 1 in the following screenshot).

Companies with a large number of item plans extending into the distant future, such as those with sales orders placed far in advance of the needed date, may choose to exclude this demand from planning by specifying the planning horizon. Reducing the number of item plans processed will shorten the run time of the process of regenerating inventory planning on the Regenerate Inventory Planning form. A Planning Horizon value of 0 will not restrict any incoming item plans, and all records will be processed during the process of regenerating inventory planning on the Regenerate Inventory Planning form.

The Time Fence box has been renamed to MPS Time Fence in the MPS section on the Inventory Planning Preferences form (Item 2). The label name was changed to indicate that the specified value applies only to master production schedule (MPS) records and is not generic across all planning records to be processed.

After an upgrade to 2024.1, 0 is specified in the Planning Horizon box on the Inventory Planning Preferences form. We recommend that users carefully consider what planning horizon best fits their planning needs before changing the predefined setting in their production environment.
