To Customize a Field on the Graph Level

If an attribute is added to a field declaration within a graph, the common business logic of this attribute is applied to each data record of this type on the graph level for only this graph. Therefore, if multiple MYOB Acumatica forms contain controls for the same field, a change of an attribute of the field within the graph modifies the behavior of a single control for the field on only the form for which the graph provides business logic.

Because the goal of customizing a field on the graph level is to change the behavior or appearance of a specific control for the field on a specific form, you start the customization of a data field from the form.

To customize a field on the graph level, perform the following actions:

1. Open the form in the browser and make the control visible on the form.
2. On the form title bar, click Customization > Inspect Element to launch the Element Inspector.
   Note:

   If you need to activate the Element Inspector for a pop-up panel, a dialog box, or another UI element that opens in modal mode and makes the Customization Menu unavailable for selection, you can click that element while pressing Ctrl + Alt.
3. On the form, click the control to open the Element Properties Dialog Box dialog box for the control.
4. In the dialog box, click Customize.
5. If there is no currently selected customization project and the inspector opens the Select Customization Project Dialog Box, select an existing customization project or create a new one.

   If the customization project does not contain a changeset for the form, the Customization Project Editor adds to the project a Page item for the form, to keep the changeset to the ASPX code of the form in the database. The container of the control is opened in the Screen Editor, and the control is selected in the Control Tree of the editor.

6. Click the Attributes tab item, which is used to review and customize the attributes of the DAC field that is bound to the control currently selected in the Control Tree.
7. Click Override on Screen Level to create in the graph extension the code template, which includes the original attributes of the field and the DACName_FieldPropertyName_CacheAttached() event handler, which replaces the attributes within the graph.

   If the customization project does not contain an extension for the graph, the Customization Project Editor adds to the project a Code item for the graph extension, to keep the code in the database. Then the MYOB Acumatica Customization Platform opens the Code item in the Code Editor, and you can start the customization of the field on the graph level.

In the graph extension, you can define the field attributes as you need to. However you can use one of the following approaches to customize the attributes of a field on the graph level:

• Define a new set of custom attributes to replace the original attributes of the field (as in the created template).
• Use the PXCustomizeBaseAttribute, PXMergeAttributes, PXRemoveBaseAttribute, and PXCustomizeSelectorColumns attributes to customize the original attributes of a field instead of replacing it with custom ones.

We recommend that you use the second approach, which is described in Customization of Field Attributes in DAC Extensions.

When you click Save on the Code editor toolbar, the editor updates the Code item in the database.
