When loading assets via the CSV loader, error
XSP xx not allowed for inventory xxxx
If the XSP should be allowed for that asset type, in the Elements form (Network Manager / Network Management / Elements, module NM0105) and make a note of the subclass of the relevant section.
In XSP and Reversal Rules (Asset Manager / Asset Reference Data / XSP and Reversal Rules, module NM0305), enter the network type, subclass and XSP value, click in the Allowable Asset Items section of the form and press F8 or click the Execute query button in the toolbar. Ensure the asset type you're loading is in the list.
If the asset type isn't in the list, add it here, save your changes and retry the load.
