Column Properties dialog: Write Back tab

Use this tab of the "Column Properties dialog" to set the properties of a column that affect writing back values to the data source to expose the write-back capability in tables. To use write back, you must also use the Table Properties dialog: Write Back tab. Write back is not available for hierarchical columns.

For more information, see "Modifying Values and Performing Write Back".

This dialog is also displayed as:

Write Back Settings dialog

Components

Enable Write Back

Use this box to allow users to modify values in the column, if the following are true:

• If the column has been enabled for write back in the repository.

• If the column has a data type of measure, text, or date and time.

  Use care when allowing users to enter decimal values. Presentation Services simply sends the value that the user types to the Oracle BI Server, which must be configured to handle users by locale. For example, the Oracle BI Server must be aware of the locale for each user, so that it can properly handle a decimal value that includes either a period or comma as a decimal separator.

If the column has not been enabled for write back in the repository, then the Enable Write Back box is disabled.

When you select this box, additional options for write-back are displayed.

Text Field Width

Use this box to select the width for the text field where users enter values, for text columns. Use the box to scroll among the values.

This box is not available on the Write Back Settings dialog.
