Redundancy reduction can be performed in cross-references, meaning that unnecessary information can be removed automatically, to get shorter and more concise cross-references . The sheet number can for example be omitted when referring within the same sheet.

 

Five parts can be subject to such redundancy reduction. They are:

 

•Plant

•Location

•Sheet

•Document number (drawing number)

•Document kind Classification Code (DCC)

 

There is also an additional setting available, to control how the reduction for the mentioned five parts should be performed:

 

•Also inside cross-references

 

A general description with an example of how redundancy reduction in cross-references work, is found below.

 

 

Example

 

You have a composition of cross-references as shown below. A help symbol in the current sheet has a cross-reference to a corresponding main symbol, which is located in sheet 03, column 2.

 

Cross-reference composition:

 

=Plant +Location /Sheet .Column

 

Title field of the sheet where the main symbol is located:

 

 

Title field of the current sheet, where the help symbol is located:

 

 

The resulting cross-reference in the help symbol will be:

 

=10+E01/03.2

 

In the help symbol, the entire cross-reference =10+E01/03.2 would be visible, if no redundancy reduction was used. If you, however, specify that redundancy reduction should be performed for plant, location, and sheet number, the result will be somewhat different.

 

Those three parts should then not be part of the cross-reference, if the same value is specified in the title field.

 

The cross-reference in the help symbol would then become:

 

/03.2

 

The reason for that is that plant and location do match the title field of the current drawing sheet. They can therefore be omitted. The sheet number, on the other hand, does not match the title field of the current drawing sheet, and will therefore remain in the cross-reference.
