columnReadOnly (dataextcols.p)

Returns TRUE if a specified column is READ–ONLY in the SmartDataObject, that is, if it is not in the list of updateable Columns.

Parameters:

INPUT pcColumn AS CHARACTER

The column name of the RowObject temp-table that is being queried.

Returns: LOGICAL

Notes: A visualization can use this dynamically to determine whether the field should be updateable on the screen. Even still, there might be circumstances where it is desirable to have it updateable on the screen but if it is READ–ONLY in the SmartDataObject, any changes sent back to the SmartDataObject will not be made in the RowObject temp-table and, therefore, in the database.
