This procedure assumes that you have already created the data object design (.datadesign) and generated the initial data object store (.data).
1 In the layout editor, right-click in an empty area of the data object design, then choose Enable Incremental Update.
3 In Target data file name, type a temporary .data file to which to write the new data. This step is required because a file saved in the file system cannot be read and written to at the same time.Figure 3-16 shows an example of values specified in Incremental Update. In this example, Employees.data is the file to update, and Employees_Temp.data is the temporary file to which to write the new data.
Figure 3-16
4 In Input Parameters, provide the parameter values to specify which data to add to the .data file. Figure 3-17 shows an example of a parameter that displays a list of values from which you select a year or years whose data to add.
Figure 3-17
5 In Navigator, delete the original .data file. In the example shown in Figure 3-16, you would delete Employees.data.
6 Rename the temporary .data file to the name of the original .data file. In the example shown in Figure 3-16, you would rename Employees_Temp.data as Employee.data.
