You can also configure the types of the appointments to be exported to the planning board via the PSA_PLB_ACTIVITY_FILTER variable. The format of its value is <include>!<exclude>. The types referenced in the optional exclude list are removed from those in the include list.
There are two special keys for specifying multiple types:
#PLN refers to appointments of all types for which the “To be released” flag is set.#FRE refers to appointments of all types for which the "Free" flag is set.
Examples:
#PLN: Exports only plannable types (this is the default).!#FRE: Exports all types except the free ones (such as MILESTONE).!HOMEOFFICE,MILESTONE: Exports all types except HOMEOFFICE and MILESTONE.SVC_ACTION,MAINTENANCE_ACTION: Exports SVC_ACTION and MAINTENANCE_ACTION only.
