Description

sm_get_tv_bi_data obtains the before-image values for the specified field and occurrence, from the point of view of the specified table view.

These routines are not to be used when previous release behavior has been set by calling sm_tm_old_bi_context. However, if the table view name is supplied, it will be used, despite the sm_tm_old_bi_context setting.

To obtain the table view containing the specified field, use fieldName\xde tv as the tv parameter.
