• Normal: Set up a normal UDF when you want to add any of the following types of fields: character, numeric, date, logical, memo, or date/time field.

• Calculated: Set up a calculated UDF when you want PCS Axis to perform calculations based on expressions you set up for the UDF.

• Milepost: Set up a milepost UDF when you want to assign a different milepost format to one or more facility types on a pipeline.

• Standard Picklist: Set up a Standard Picklist UDF when you want to limit data entry to a list of valid choices in a selection list. (A Standard Picklist in PCS Axis is similar to a validation table in PCS 7.)

• Dynamic Picklist: Set up a Dynamic Picklist with a drop-down list of data items that change based on a data item selected in another picklist. This type of picklist uses a cascading parent/child relationship allowing you to set up more than five (5) levels of interdependent picklists.

• On/Off Pair: Set up a custom pair of on/off fields when PCS Axis does not provide a pair of installed on/off fields for recording inspection readings in a data grid or form. This UDF is available for both facility and continuous surveys.

• Summation: Set up a Summation UDF when you want PCS Axis to perform an aggregation for a selected Information, Inspection, or Maintenance field. This UDF type supports aggregation on a user-selected target field using any one of the following operators: Average, Count, Latest, Maximum, Minimum, and Sum. You can also include one or more user-defined filters in the set up of the UDF to further filter the results of aggregated data. Summation UDF is a Permanent Information field available for use in data grids, forms, reports, and as a filter in scheduling.
