Item Assembly Structures for Assets

Last Updated on November 19, 2022 by maximosecrets

Item Assembly Structures are used for three purposes:

This article considers item assembly structures when used with assets.

An Item Assembly Structure (IAS) is a hierarchy of items, both rotating and non-rotating, which describe the sub-assemblies and spare parts which can in this example of the use of an IAS be applied to an asset to form an asset assembly structure.

It is only in the Item Master application where the Item Assembly Structures are created. The item will have to be a rotating item to have it applied to an asset, the asset will need to reference the rotating item.

There is an action called “Copy Item Assembly Structure” which derives a list of existing item assemblies that you might want to apply to your current item. I will copy the item assembly that is on the PUMP100 item.

The item assembly structure that has been copied consists of 7 items and the quantities of the item required. The remarks field might be used to indicate the position of the item. 

Some of the items might also consist of children. On the Item’s detail menu there is a “Move To xxx” action where xxx is the item number. This transfers the item to the Current Level field which allows you to see the children of this item. MOT10 belongs to the top-level item, in this case AJE05.

It is only rotating items which can have child rotating items. If you attempt to add a rotating item as a child to a non-rotating item, you will receive the error message “BMXAA2105E – A non-rotating item may not have a rotating child item.”

In the Assets application there is an action called Apply Item Assembly Structure which requires you to provide an asset number for any rotating items that exist in the item assembly. In this example MOT10 is a rotating item, and so we need to create an asset number for it, I have used the “Autonumber All” button which will create asset 2173.

Once applied the rotating items in the item assembly structure become assets and are seen in the Subassemblies table window, asset 2173 has now been created. The non-rotating items are copied as spare parts along with their quantities and remarks.

In the Subassemblies table window, you can use the “Move to xxx” from the details menu to make the subassembly asset the focus for the asset record, in this case asset 2173. The Spare Parts tab now shows the subassemblies and spare parts of this child asset, in this case the one item 117021 with a quantity of 2.

There are a few points to note with regard to an Item Assembly Structure:

In the Receiving and Shipment Receiving applications you can receive a quantity of assets which require serialization. In this example the Receive Rotating Items action is used in the Receiving application when the received item on a purchase order line has reached WASSET status. The Autonumber button has been used to create asset 2175. The button at the right-hand end of the table window is Apply IAS. Note. If there are multiple assets you can also apply the IAS, but you need to do it to each asset in turn.

The Apply Item Assembly Structure dialog that opens is the same as you have seen before.

It is the use of the Autonumber All button in several places in Maximo which is why I much prefer to suggest to clients that the asset number, at least for rotating assets, is a generated number rather than bearing any specific meaning. Often the meaning attributed to the asset number is representing the sort of data contained on the location record where the asset exists.

You will not be able to use the Apply Item Assembly Structure action in the Assets application on an asset record that does not reference a rotating item, you will receive the error message “BMXAA0172E – Cannot apply IAS. A rotating item is not available.”

And finally, a couple of points with regard to tool items.
