This is controlled by the template item and the link to the inspection template setup in Template edit.
Task/Linked Inspections are generated 7 days before the Estimated Date of the Task they are linked to. There is also an assessment done on Schedule if an inspection record is required and is missing, it'll generate. This is to cater for shorter term changes like reassignment of Supplier etc. We always ignore the Resource Code and Frequency in the Policy assigned to the Inspection for this Inspection Type. Task Inspections also are not affected by Inspection Policies, and a single generic Policy can be used for all Task Inspections.
