About Metrics resolver

Beneath each Metrics KPI are the field resolvers. These tags represent fields that you can link to their data sources.

When you link a field to a formula,AVEVA™ Production Management automatically populates the field with resolvers beneath the field. There is a resolver for each tag that appears in the formula. Link each resolver to a field in a data source so that AVEVA™ Production Management can retrieve the data and use it in the expression for the formula.

When the field calculates, it retrieves records from the SourceLocations for the periods being calculated, then reduces those records based on the WhereCondition, and then performs the ResolverOperation on values in the remaining SourceFieldName field. The result is a single scalar value that the field algorithm uses.

Resolvers are considered server-side filtering and therefore take the "invariant" version of filtering.

• Invariant form

• Names used in filter are required to be a column name

• Uses ISO 8601-compliant UTC dates
