Scales

Information

• In modules, the scale must always be customized above the corresponding scale objects.

Time Scale

Information

• Time scale data items form time scales under which time-related objects (e.g. bars, number values etc.) can be positioned.
• A scale DI always represents a grid for a scale area.
• scale areas are formed from several scale data fields.

Creating a scale-DI

• Create a time scale DI with Class = 3 for DT400 Other objects in the Data Dictionary module
• Allocate a time scale to the newly created time scale-DI
  • in the Data Items module. For sub-DIs:
    • Define functions in the Function field.
    • Allocate the symbols in this field: For this purpose, enter the required symbol ID in the SUBDI symbol ID field.

Creating a scale area

Histogram Scale

Information

• The histogram scale enables histogram bars to be displayed together with a time scale.
• Unlike time scale DIs, the histogram scale DI is not customized in a specific scale area. It is adopted to the same data area as the histogram bars.

Procedure

• Create a histogram DI with Class = 12 for DT400 Other objects in the Data Dictionary module
• DB type determines the formatting of the histogram scale grid in the module.
  • Example:
    • DF type N8 allows for a grid with decimal places.
    • DF type N4 only allows 9 digits before the decimal point and no decimal places.
• Assign the Grid Line sub DI to the histogram scale DI
  • define its function and
  • allocate the symbols
  • in the Data Items module.

Details

• The grid line is displayed as a horizontal line graduated in accordance with the data field parameters.
• The histogram scales are used together with the histogram bars for the customizing of utilization diagrams.

Scale Objects

Date Bar

Information

• Date bars are used to display the duration of , e.g., tasks in the form of bars below a time scale.
• A date bar is a complex DI, which can change its symbol depending on sub-DIs (milestone, critical, non-critical, completed, etc.).

Procedure

• Create a time scale DI with Class = 1 for DT400 Other objects in the Data Dictionary module
• In the Data Items module,
  • assign two arbitrary sub-DIs of the DF type = D (Date) to the bar DI:
    • assign a start date DI with Function = SD and
    • an end date DI with Function = ED.
  • Assign symbols. The symbol assignment defines the display of the bars in the module.
    • The required symbol in the Symbol DI field is assigned to a bar without traffic light function.
      • Example in the standard: the Requested date bar (DI002001)
    • In case the bar changes its display depending on different values (traffic light function), further sub-DIs are assigned.
      • This sub-DIs have the function A or D. Their customizing equates to the customizing of traffic light sub-DIs.
        • Example in the standard: the date bar of the calculated dates (DI002951)
        • The order or dominance of the sub-DIs is defined via the Pos. parameter.
    • A combination of both variants is possible, too. In this case
      • the sub-DI symbols overwrite the DI symbol
      • If no condition of the sub-DIs is satisfied, the DI symbol is displayed.
        • Example in the standard: the actual date bar (DI002005)
    • All sub-DIs must originate from the same or a parent data table.

Notes

• Date bars cannot be displayed without a time scale date scale, since these make positioning possible.
• Date bars are used together with time scales in scale areas for the customizing of modules with Gantt charts.

Histogram Bars

Information

• Histogram bars display values as bars below a scale. It must be possible to assign the values to a date.

Procedure

• Create a time scale DI with Class = 2 for DT400 Other objects in the Data Dictionary module
• In the Data Items module,
  • assign sub-DIs to the histogram bar DI
  • define the function
    • assign one or multiple sub-DIs with Function = T and
    • one or multiple sub-DIs with Function = W
  • assign a Symbol ID.

Notes Histogram bars can only be displayed if a data field of the “Histogram scale” type is assigned above them.

• The histogram scales are used together with the histogram scales for the utilization diagram customizing.

Linkage

Information

• DIs of this Class are used for the display of structures, especially for network structures, e.g., for links in the Gantt chart.
• A linkage data item is displayed in modules as a line between two objects. Their appearance is determined by the sub-DI symbols.

Procedure

• Create a time scale DI with Class = 8 for DT400 Other objects in the Data Dictionary module.
• In the Data Items module, assign the sub DIs to the Linkage DI
  • define the function
  • assign the Symbol ID

Details

• Customizing modules with linkage

Projection

Information

• Projection data items display numerical values under a time scale.
• Numeric values must be assignable to a date.

Procedure

• Create a time scale DI with Class = 11 for DT400 Other objects in the Data Dictionary module.
• Assign sub DIs to the projection DI
  • in the Data Items module.
    • Define the sub DIs as follows:
      • one or multiple sub-DIs with Function = T and
      • one or multiple sub-DIs with Function = W
  • If necessary, carry out the preallocation in the Summarization type field.
    • If a deviating value is entered in the field of the same name on data field level upon embedding the DI into a module, the deviating value takes effect.

Details

• The value (V) is displayed below the time scale at the position that corresponds to the date D.
• If the module construction requires multiple values to be projected, you can either create a projection DI for each value or only one protection DI with multiple sub-DIs with Function = W.
• Number formats are ineffective on projection data fields, since they are not numeric. They have to be set in the DI (function W).
