Label Validation across all Project P&IDs

The project may be set to check that all labels in all P&IDs in a project are unique within a category of item, for example, pipes or instruments.

These settings are made using the AVEVA P&ID Project Administration program, using the buttons in the Label Validation Across P&IDs sections of the Pipes - Settings Sub-Category, Instruments - Settings Sub-Category, Equipment - Settings Sub-Category, Valves - Settings Sub-Category and Miscellaneous - Settings Sub-Category.

If the Prevent option is selected, users are prevented from entering project duplicate labels for that category of item. If this is attempted, an error message is displayed and the duplicate labels may not be placed on the P&ID. The error message will identify the drawing number of the P&ID on which the other label (that the user attempted to duplicate) is located.

If the Warn option is selected, users are warned if they enter project duplicate labels for that category of item. The entry of duplicate labels is permitted in this case, but a warning message will be displayed on the P&ID, and will accompany the label data if it is transferred to AVEVA P&ID Reports. The warning message will identify the drawing number of the P&ID on which the other label (that the user is duplicating) is located.

If the Ignore option is selected, no uniqueness validation of labels across P&IDs takes place.

If Prevent or Warn options are selected, the uniqueness of labels across a project is checked against the project database.

Validation using an SQL Database

The uniqueness of labels can alternatively be checked against the database in a network location available to all project users of AVEVA P&ID. The database location is specified in the Project Configuration Category of the AVEVA P&ID Project Administration program.

Most label data is transferred to the database automatically. Some must be transferred using the Synchronise process when exporting to AVEVA P&ID Reports. Refer to Export Data to a P&ID Reports Database.

The table specifies which label values will be transferred to the database automatically and which ones will be transferred when the Synchronise process is executed.

( = Transferred; X = Not transferred)

Values deleted in a drawing will only be deleted in the SQL database once the Synchronise process is executed.

Validate Drawings Generated in other Locations

If a project is being worked on in multiple locations, the P&IDs generated in these other locations must be sent to the office in which the database is located. They must then be opened in AVEVA P&ID in order for the validation check to take place.

P&IDs can be e-mailed using the eTransmit facility (accessed from the File menu), which is available in AVEVA P&ID. Using this facility, multiple drawings can be sent in a .zip file, accompanied by a transmittal. A number of other options are also available.

Refer to the AutoCAD documentation for details.

Points to Note

• Duplicate labels that include null characters (e.g. "?") in the same positions are not validated and may be entered regardless of the project settings.

• If the Ignore option was set, but is subsequently changed to Prevent or Warn, when a project drawing is reopened or refreshed, any duplicate labels for that category of item are displayed with an error message if the Prevent option was selected or a warning message if the Warn option was selected.

• Each part of an SPP label is placed separately and may be deleted separately. If a part of an SPP label is deleted and as a result the label is now a duplicate of an SPP label on another project drawing, an error or warning message may be displayed if the Prevent or Warn option is selected in the Miscellaneous - Settings Sub-Category.
