Customizing Parameter Display
Grouping parameters (order field)
You can group the display of report parameters. A group of parameters corresponds to a MetaAttributeValue that is defined on the "Report Parameter" MetaClass and then connected to the parameters of report templates concerned.
Consider a Report Template "Org-Unit Characteristics", which contains three parameters:
"Status",
"Street Number", which can include one or no value, with a multiplicity of "0..1".
"City", which should display a mandatory value, with a multiplicity of "1".
For consistency and visibility, the following procedures detail how to display "Street Number" and "City" parameters in an "Address" group.
To create the "Address group":
1. Access the Report Parameter MetaClass properties.
2. In the MetaAttribute page, open the Displayed in Group MetaAttribute properties
3. Select Characteristics - Standard page.
4. In the MetaAttributeValues for enumerated MetaAttribute only section, click Add 
and create the MetaAttribute Value "Address".
and create the MetaAttribute Value "Address". 5. Specify an Internal Value as well as values in each data language.
6. Exit HOPEX and compile the metamodel to take account of modifications.
To connect the "Address" group to the parameters of the "Org-Unit Characteristics" Report Template:
1. In the "Org-Unit Characteristics" Report Template, select the "Street Number" parameter and open its properties.
2. Select Characteristics.
3. In the Displayed in Group field, select the "Address" MetaAttributeValue.
4. Carry out the same procedure for the "City" parameter.
Note that if both parameters have the same order number, the "City" parameter appears in the report before the "Street Number" parameter, the multiplicity "1" being positioned before the multiplicity "0..1". For more details, see Defining object display order in generated reports.To position "Street Number" before "City", modify the MEGA order number of the "Street Number" parameter:
1. In the "Street Number" properties, select General > Administration page.
2. In the Order field, enter an order number lower than that of the "City" parameter.
3. Click OK.
Defining object display order in generated reports
Parameters without groups
For parameters not containing groups, display order depends on:
• MEGA order number: objects of a list have an order number taking value "9999" by default. You can modify this value for each object (from the object properties, General > Administration page).
• Multiplicity: for parameters with the same MEGA order number, display order depends on multiplicity:
• 1. Multiplicity 1
• 2. Multiplicity 0..1
• 3. Multiplicity 1..*
• 4. Multiplicity * and NONE (the two are equivalent)
• Alphabetical order: for the same multiplicity, it is alphabetical order that is taken into account.
Parameters with groups
The parameter group display order depends on group alphabetical order.
In each group, parameters are displayed in MEGA order.
If parameters of the group have the same order number, their display order depends on their multiplicity:
• 1. Multiplicity 1
• 2. Multiplicity 0..1
• 3. Multiplicity 1..*
• 4. Multiplicity * and NONE (both are equivalent)
For the same parameter multiplicity, it is alphabetical order that is taken into account.
Parameters with and without group
Parameters that are not in groups appear in first position. They are followed by groups.
