Disassembly Wizard

Navigation: Transactions >> Inventory >> MO Entry. GoTo Button >> Disassembly Wizard

The Disassembly Wizard can quickly create a Disassembly Order when provided a Lot Number, Serial Number, or Manufacturing Order.

For example, when provided with a Serial Number, the wizard locates the originating LeanMFG manufacturing order, then uses the Inputs from that transaction to calculate what the outputs should be from disassembling the given serial number. If serial-lot linking was performed on the originating MO, that information will be used to pre-enter serial/lot numbers for the disassembly order.

To use the Disassembly Wizard you must have an MO Document Type defined for BOM Type = Disassembly. See LeanMFG Setup.

Costing

If you are using an Actual Cost method (FIFO or LIFO Perpetual, or Average), Disassembly Wizard will create the disassembly transaction using the same costs as were recorded on the original MO.

If you are using a Standard Cost method (FIFO or LIFO Periodic), Disassembly Wizard will create the disassembly transaction using the current Standard Costs.

Disassembly in an Actual Cost environment can result in large cost variances.

For example, as shown above, a recent MO produced 1-unit of 256 SDRAM at a cost of $304.20. However, there were 10 units already inventory valued at $247.50.

The Disassembly Transaction (above) will be created using the $304.20 cost from the original MO. The original Inputs (which are now the Outputs) will also be entered using their original costs (which total $304.20).

However, when GP pulls 1-unit of 256 SDRAM out of inventory, it will do so using the Valuation Method assigned to the item, which in this case is FIFO Perpetual. That means the cost of 256 SDRAM when it comes out of inventory will be $247.50.

Since the Inputs go back into inventory at their original costs, totaling $304.20, but 256 SDRAM only put $247.50 of cost into WIP, this leaves a variance of $56.70 (shown above).

A similar type of variance can be created with Standard Cost items if the standards have changed since the original MO and the component costs do not add up to the finished good cost.

Disassemble Serial/Lot Number

If you frequently disassemble finished goods you should consider using serial/lot linking so the wizard can more accurately select output components. Serial/Lot Linking will allow the wizard to locate the specific component serial/lots used to build the finished good item, and they will be selected as Outputs.

If Serial/Lot Linking is not used, the wizard will add the entire picklist from the source MO to the disassembly Outputs. You may need to adjust quantities and/or serial/lot selections on components.

Disassemble: Select “A Lot Number” or “A Serial Number” depending on whether the Item is Lot Tracked or Serial Tracked. You cannot use “A Manufacturing Order” for serial/lot tracked finished goods.

Item Number: Select the Item Number to be disassembled.

Serial/Lot Number: Enter the serial/lot number or select it from the lookup. The serial/lot number must be available in inventory. The MO Number field (adjacent to the Serial/Lot Number field) will display the Manufacturing Order that produced the selected serial/lot number. If the wizard cannot locate an MO, the field will remain blank, and you will need to manually create a disassembly order.

If the Lot quantity was split (i.e. a receipt of 200 was split into 199 and 1 so that Dynamics GP can accurately allocate costs), the Disassembly Wizard will create the disassembly using one of the split layers, and you will need to manually adjust the Input quantity to account for the total quantity of the Lot Number. See the Split Cost Layerssection of this manual for more information.

Draw From Site: Defaults to the Site containing the serial/lot number.

Post To Site: Defaults to the Post To Site from the originating MO.

Quantity: Defaults to the MO Quantity (for Lots) or 1 (for Serials).

Process: Click the Process button to create the Disassembly transaction.

You must have a MO Document Type where the BOM Type is Disassembly. The Wizard will check setup and will not continue if the necessary setup does not exist.

The Wizard will create a “Manual MO”. This is a manufacturing order that does not have a Bill of Materials. As a result, after the MO has been created, any changes to quantities must be performed manually—the Picklist cannot be automatically recalculated.

Disassemble Manufacturing Order

Disassembly Manufacturing Order will create a Disassembly Transaction using a source Manufacturing Order. In short, the original Inputs become Outputs, and the original Output becomes and Input. Note that a multi-product Manufacturing Order cannot be used as the source MO—it must be an MO with a single Item output.

Disassemble: Select “A Manufacturing Order”. You cannot use “A Manufacturing Order” for serial/lot tracked finished goods. Those must be disassembled individually using the Serial Number or Lot Number disassembly methods.

MO Number: Select the MO Number to be disassembled.

Draw From Site: Defaults to the Post To Site from the MO.

Post To Site: Defaults to the Post To Site from the MO.

Quantity: Defaults to the MO Quantity.
