The Inspection Auto-Selection feature allows you to automatically assign an Inspection to a Degradation Mechanism Evaluation (DME) in RBI 581. By default, this feature is disabled. You can enable the feature by accessing the Inspection Auto-Selection workspace.
For each DME for which you want GE Digital APM to assign Inspections automatically, an RBI Inspection Auto-Selection Criteria record must exist. This record stores the following details:
The analysis that is performed on the DM
The DM methodology of the DM
The equivalent DM methodology
The years of Inspection History to be considered while linking Inspections
The following table provides a list of baseline RBI Inspection Auto-Selection Criteria records and their field values. You can access these records only after you enable the Inspection Auto-Selection feature.

When you create, duplicate, or apply an RBI 581 Risk Analysis, all the Inspections that meet the criteria specified in the RBI Inspection Auto-Selection Criteria record are assigned to the DME automatically.
The maximum number of Inspections that can be assigned to RBI 581 Cracking Damage Evaluation or RBI 581 External Cracking Damage Evaluation is six. Therefore, among the Inspections that meet the criteria specified in the RBI Inspection Auto-Selection Criteria record, only the latest six Inspections are assigned to the DME. Similarly, the maximum number of Inspections that can be assigned to the 581-Atmospheric Tank Bottom Corrosion DM is one. Therefore, only the latest Inspection (among the ones that meet the criteria) is assigned to the corresponding DME.
Note: Inspections are also assigned automatically when you create an RBI 581 Risk Analysis using the Risk Based Inspection (RBI) 581 Data Loader.
Even after you delete an RBI Inspection Auto-Selection Criteria record, Inspections are automatically assigned to a DME. These Inspections, however, are not filtered based on the criteria specified in the record.
Suppose you have created an RBI 581 Risk Analysis on 17th March, 2017, which is linked to the 581-Amine Corrosion DM.
The following RBI Criticality Auto-Selection Criteria record is used to assign Inspections to all the DMs that are linked to RBI 581 Thinning and Lining Evaluation (which includes 581-Amine Corrosion).

Among the Inspections in the previous table, the following Inspections are not assigned to 581-Amine Corrosion because they were completed more than 20 years ago:
Insp-3
Insp-5
The remaining Inspections are automatically assigned to 581-Amine Corrosion because they satisfy the following conditions:
They are linked to a DM that belongs to either RBI 581 Thinning and Lining Evaluation or Criticality Int Corr. Deg. Mech. Eval.
They were completed less than 20 years ago.
Now, suppose you have created an RBI Inspection Auto-Selection Criteria record with the following details:

Suppose you have created another RBI 581 Risk Analysis on 17th March, 2017, which is linked to 581-Amine Corrosion.
In this case, only Insp-1 will be assigned to 581-Amine Corrosion. Although Insp-4 is also linked to 581-Amine Corrosion, it will not be automatically assigned to the DM because the Inspection was completed more than 10 years ago.
