Operators and applicability codes for IETMs
You can restrict the inventory to which IETM technical references and attachments apply by specifying an applicability range. Also, you can specify the operator for which each IETM reference and attachment applies. Therefore, in a single task job card definition, you can have several IETM technical references that each apply to different operators and/or different subsets of inventory. When the job card definition is initialized into actual tasks, each task includes only the IETM technical references that have the same applicability range and the same operator as the inventory to which the job card task applies.
If you modify an inventory's operator or applicability code, planned tasks on that inventory are updated to the correct IETM technical reference upon saving changes to the inventory. For example, if you add an operator to an aircraft inventory item, all of the planned tasks that apply to the aircraft, its sub-assembly, and sub-inventory are updated with technical references or attachments, specific to the operator and applicability range.
