This section will cover how to Add/Change/Remove asset types registered in your ALIS instance and was added to the release in ALIS v2022.01. Asset Type management is part of the basic features of ALIS and is provided withing the ALIS basic subscription.


We have added the familiar methods of ALIS configurations to the Asset Types. This now allows you to get a better overview and management capabilities to it, including excel based Export/Import of it.  

Asset Types overview

You can find the configuration page and asset type overview under your general "Settings"> Asset Types > Manage asset types

Here you can 

  • Search for specific asset types
  • Edit an Asset Type
  • Delete asset types ( if no assets are associated with the asset type*) 
  • Create a new asset type
  • Export the complete asset type list with it's main properties

*To associate an asset with a different Asset Type > Export and Import the corresponding assets and modify the assetClass field to the new pre-excisting asset type.

Create / Edit an asset Type

When creating or editing an asset type you can add or edit some predefined properties. See the section "Adding/Changing  Asset Types - minimum requirements" for more details on what fields are mandatory.

You can upload new pictures to overwrite the current image.

Preventive Maintenance tasks for Asset Types

Here you can define what the preventive maintenance tasks are and with which maintenance regime they should be performed. 

(info) The colour of each asset in the Map will reflect the proportial maintenance status of that asset as defined to it's preventive maintenance task interval for that asset type. Always the worst condition will be shown (unless filtered otherwise) .

See How-to change the preventive maintenance cycle of an asset(-type) in ALIS for more information on the subject.

We have added a handy quick-select for the most common maintenance regimes but feel free to make it custom. 

To add a new Preventive maintenance task - Select the task from the drop down - select a maintenance interval and hit the "+" button. 

To add new maintenance tasks to the dropdown see - ALIS - Maintenance tasks configuration

Export function 

To Export the complete set of asset types currently in the system - find the °°° top right and select Export Asset Types.

You can now edit ( see later)  the excel sheet and the asset types properties to your liking. Do not modify or re-use the "id" of the asset types.

You can add new asset types in batch by adding additional lines into the sheet.
(warning) WARNING : for new asset types in the excel sheet - leave the "id" column empty for those new lines. The system will add a new "id" automatically for each new asset type. 

Import function

With the previously exported and edit asset types from your system you can use the °°° to open up the "Import Asset Types"

You can now drag and drop the asset type excel sheet in the dropbox and also any images you used as a reference in the excel sheet.

Once all files are dropped - you can Analyse the file and validate it for import

(info) You can now only Create/Update asset Types by excel import. To remove Asset types, remove them 1by1 from the asset overview.

When updating asset type data in your system it's always good to have a copy of the export in case you would modify details unwillingly) 

(if all would be going wrong - don't worry -  you can always contact us so that we can playback an automatic backup of your instance to a certain date of choice)
