Purge Distance Engine Cache

Purge Distance Engine Cache is initiated from the Supplementary Purge using Request Type "PDEC".

It is recommended that the distance cache be purged when installing a new version of a distance engine. Otherwise, newer (and presumably more accurate) values will not be retrieved from the distance engine.

It is also recommended that the distance cache be purged when switching the Distinct Distances and Transit Times by Direction flag in the global settings.

When triggering the Purge Distance Engine Cache, a distance engine must be selected. This function will delete all entries in DST_CACH_T and DST_CACH_BRKD_T associated to the given engine that are not overrides. Note that, for this purge, the Cut-off Date will not apply.
