PeopleSoft :: Dynamic Prompting-Edit Table method

PeopleSoft enable us to use the Dynamic Prompting in two ways.
1)DERIVED record fields or popularly known as Edit Table method
2) Dynamic Views.

DERIVED record fields or popularly known as Edit Table method

There can be business case where based on the value on one field, the prompt for other field should change. The change may include the search fields or list box values displayed on the prompt page. It can also demand an entirely different data set to be prompted for the user. In this type of scenarios the action that we require at the back end is to point the prompt of the fields to different tables or views. To tackle this kind of scenarios you need to use derived work record fields.

Consider the case where you have a check box (called effective dated) and a department field on the page. If the check box is checked you need to show only all the effective dated departments on the prompt. Otherwise the prompt should list all the department codes and user should also have a search option to search with the effective date. This is an ideal scenario where you can use derived record field method.

Please follow these steps :
1)Add the field checkbox to your main record
2) Create a view, say PPSFT_DEV0002_VW, which will fetch the effective dated departments.
3) Create another view, say PPSFT_DEV0003_VW, which will fetch all the departments. Make sure to check the alternate search key and list box item property for the EFFDT field (this is for the stated requirement. You may have to create both the views as per your real requirement).
4)On the record field properties of the field department, give the prompt table name as %EDITTABLE (it is not mandatory to give %EDITTABLE all the time. You can give % and any field name present on the table DERIVED).

Please find the code snippet that is to be added to the field change event of the field Check box in your main record

/* If it is checked then use first view else use second view */
WinMessage("Hi", 0);
If Record.PPSFT_DEV0002.CHECK_BOX.Value = "Y" Then
/*Specify the prompt record name here. Appropriate field name should be used in place of EDITTABLE
PPSFT_DEV0002_WRK.DEPTID = GetRecord(Record.PPSFT_DEV0002_VW).GetField(Field.DEPTID).Value;
Else
PPSFT_DEV0002_WRK.DEPTID = GetRecord(Record.PPSFT_DEV0003_VW).GetField(Field.DEPTID).Value;
End-If;*/
DERIVED.EDITTABLE.Value = "PPSFT_DEV0002_VW";
Else
DERIVED.EDITTABLE.Value = "PPSFT_DEV0003_VW";
End-If;
Place the field EDITTABLE (or other fields which you have mentioned in the previous step) to the page where your department field is present. This is mandatory because we will be referencing the field in PeopleCode program in next step. To reference the field in PeopleCode, it is required that the work record field is present on the component buffer. You can hide this field, because it will not make any sense to the business user.
The Edit table that we are placing as invisble on the page should have record name as DERIVED and Field Name as EDITABLE

Even we can try the same code with field default event and see what difference it makes.
