There was a user who requested the "Manufacturer" field to be available under Assets reports. Currently it is only available under "Assets by Product type" present on the Reports page.
In this, the Manufacturer under "Customization - Asset Management - Product" mapped to Asset will be displayed.
The user can also make use of the below Query:
SELECT productType.COMPONENTTYPENAME AS "Product Type", resource.RESOURCENAME AS "Asset Name", product.COMPONENTNAME AS "Product", productType.COMPONENTTYPENAME AS "Product Type", aao.NAME AS "Vendor Name", state.DISPLAYSTATE AS "Asset State", rCategory.CATEGORY AS "Asset Category", rtype.TYPE AS "Asset Type", product.MANUFACTURERNAME AS "Manufacturer" FROM Resources resource LEFT JOIN ComponentDefinition product ON resource.COMPONENTID = product.COMPONENTID LEFT JOIN ComponentType productType ON product.COMPONENTTYPEID = productType.COMPONENTTYPEID LEFT JOIN ResourceType rtype ON productType.RESOURCETYPEID = rtype.RESOURCETYPEID LEFT JOIN ResourceCategory rCategory ON productType.RESOURCECATEGORYID = rCategory.RESOURCECATEGORYID LEFT JOIN VendorDefinition resourceVendor ON resource.VENDORID = resourceVendor.VENDORID LEFT JOIN SDOrganization aao ON resourceVendor.VENDORID = aao.ORG_ID LEFT JOIN ResourceState state ON resource.RESOURCESTATEID = state.RESOURCESTATEID LEFT JOIN ResourceLocation resLocation ON resource.RESOURCEID = resLocation.RESOURCEID WHERE (resLocation.SITEID IN (2)) ORDER BY 1;
