PROCESS EQUALS

Applies to: CELONIS 4.0 CELONIS 4.2 CELONIS 4.3 CELONIS 4.4 CELONIS 4.5 CELONIS 4.6

Description

PROCESS EQUALS matches the variants of a process based on simple expressions. PROCESS EQUALS is less powerful than MATCH_PROCESS_REGEX and MATCH_PROCESS but it is also simpler to use.

Syntax
PROCESS [ ON activity_table.activity_column ] [ NOT ] equals [ start ] activity ( to activity )* [ end ]

  • activity_column: string column joinable to the activity table (Since: CELONIS 4.6)

  • equals: EQUALS | #

  • start: START | ^ (The case has to match from the start)

  • end: END | $ (The case has to match till the end)

  • to: TO | ->

  • activity: ANY | * | single_activity | grouped_activity

    • single_activity: [LIKE] activity (Activity name. LIKE allows you to use wildcards in your activity name)

    • grouped_activity: single_activity (, single_activity )*

If the activity name does not exist, then a warning is displayed. In this scenario PROCESS EQUALS will have no matches, and PROCESS NOT EQUALS will match everything. (Since: CELONIS 4.6)

Examples

[1] PROCESS EQUALS to filter down to cases where activity 'A' is directly followed by 'B'. Where in the case the activity 'A' is followed by 'B' doesn't matter in this case.
