Edit Item Data

Note: Items can also be edited by importing differences from an Excel spreadsheet, or by using the Compare/Update facility.

Data may be edited by the user in the tabs, either by entering data directly into a field, or by selecting a value from a list.

If a list of values is available for a cell, only values from that list may be entered in that cell.

Note: Whether or not data can be entered directly into a cell, or must be selected from a list of values, is dependent on settings in the AVEVA P&ID Project Administration program.

Certain values or combinations of values must be unique for an item or type of item in the database. For example, tag numbers. If a change to data in the tabs results in such values being duplicated, a message will be displayed to inform the user of this, and the change will be prevented.

Note: As well as the standard AVEVA P&ID attributes, user-defined attributes (UDAs) may be defined for items in the AVEVA P&ID Project Administration program. If a user-defined attribute is measured in units, such as a distance, there will be a default unit of measure selected for it, e.g. metres.
If required, users can choose for an individual item to the display units and unit values for a UDA in different units of measure from the default. For example, they may choose to display a distance in kilometres instead of metres.
Unit values will automatically adjust to reflect the select unit of measure (for example, if changed from metres to kilometres, the value will be divided by 1000).

Refer to Appendix - Editable and Non-Editable Attributes in P&ID Reports for lists of editable fields.
