How to Clear a Field Value in PeopleCode?

In PeopleCode, clearing a field value means removing the existing data from a field or setting it to a null state. This operation is commonly required when developing or customizing PeopleSoft applications. In this article, we will explore the various methods to clear a field value in PeopleCode and answer some related questions.

How to Clear a Field Value in PeopleCode?

The most straightforward way to clear a field value in PeopleCode is by using the built-in function called FieldDefault. By invoking this function, you can set the field value to its default value, effectively clearing any existing data. Here’s an example:

“`PeopleCode
&record.FIELDNAME.Value = FieldDefault(&record.FIELDNAME);
“`

By executing this code, the field value will be set to its default value, which could be an empty string or a specific value defined in the field’s properties.

Related FAQs:

1. How to clear multiple field values in PeopleCode?

To clear multiple field values simultaneously, you can iterate through an array of field names and call the FieldDefault function for each field.

2. Can you clear a grid field value in PeopleCode?

Yes, you can clear a grid field value using the same approach as mentioned above. Just specify the grid and field names accordingly, e.g., `&grid.GetRow(&rowNum).GetRecord(Record.RECORDNAME).FIELDNAME.Value = FieldDefault(&record.FIELDNAME);`.

3. How to clear a field value on a page when a button is clicked?

You can associate an appropriate PeopleCode event with the button and add the code to clear the field value within that event.

4. How to clear a field value on a page when a checkbox is unchecked?

Use the appropriate PeopleCode event associated with checkbox interaction (such as OnRowSelectChange in a grid) and add the code to clear the field value when the checkbox becomes unchecked.

5. Can you clear a field value conditionally?

Yes, you can add conditional statements to determine when to clear a field value. For example, you can use an If-Then-Else construct or a Case statement to execute the clearing code based on certain conditions.

6. How to clear a field value only if it is not already null or empty?

You can first check the field’s value using an If statement and then conditionally execute the clearing code only if the field value is not already null or empty.

7. How to clear a field value using the built-in functions?

Aside from FieldDefault, you can also use SetDefault or SetDefaultForUser functions to clear a field value. However, FieldDefault is the most commonly used method.

8. Can you clear a readonly field value in PeopleCode?

No, you cannot directly clear a readonly field value. However, you can set the readonly field to a different value, such as its default value or a specific predefined value, to give the illusion of clearing the field value.

9. How to clear a record field value in PeopleCode?

You can access a field within a record by using the Field method and then use the FieldDefault function to clear its value. For example, `&record.GetField(Field.FIELDNAME).Value = FieldDefault(&record.FIELDNAME);`.

10. How to clear a field value in a component interface?

You can use Component Interface PeopleCode to clear a field value by setting it to its default using the FieldDefault method. Examine the Component Interface documentation for the specific syntax to access fields and execute PeopleCode.

11. Can you clear a search record field value in PeopleCode?

Yes, you can clear a search record field value in PeopleCode by using the FieldDefault function, similarly to clearing a regular record field value.

12. How to clear a field value programmatically without a user’s interaction?

To clear a field value programmatically without user interaction, you can add the code within a PeopleCode event that is triggered automatically during a specific event, such as component processing, page activation, or row insertion.

In conclusion, clearing a field value in PeopleCode is a common requirement in PeopleSoft development. By utilizing the FieldDefault function and understanding how to apply it in different scenarios, developers can effectively clear field values and tailor the behavior of PeopleSoft applications according to their needs.
