The BPM tool provides additional formula functions.

Formula script can be utilized in conditions, script tasks, various task actions. Some functions can be used in a workflow (broadcastSignal, startProcess).

bpm\targetEntity\attribute

bpm\targetEntity\attribute(ATTRIBUTE)

Fetches an attribute value of a target record.

bpm\createdEntity\attribute

bpm\createdEntity\attribute(ALIAS_ID, ATTRIBUTE)

Fetches an attribute value of a record created within a process. ALIAS_ID can be obtained from the detail view of Task, that has an action creating a record.

bpm\processEntity\attribute

bpm\processEntity\attribute(ATTRIBUTE)

Fetches an attribute value of a process record.

bpm\startProcess

bpm\startProcess(FLOWCHART_ID, TARGET_TYPE, TARGET_ID, [ELEMENT_ID])

Starts a process. Available since Advanced Pack v2.5.2.

Example:

bpm\startProcess('flowchart-id', 'Account', 'account-id');

bpm\broadcastSignal

• bpm\broadcastSignal(SIGNAL_NAME) – broadcast a regular signal (as of v2.7.1)
• bpm\broadcastSignal(SIGNAL_NAME, ENTITY_TYPE, ENTITY_ID) – broadcast an object signal (as of v2.8.5)

It can be useful to broadcast a custom signal from a worfklow rule and then catch it inside a running process. A workflow rule will perform some condition checking and only after than will broadcast a signal.

Example (regular signal)

$signalName = string\concatenate(
    'notePostedInCaseBySupportManager.',
    entity\attribute('id')
);

bpm\broadcastSignal($signalName);

Then it will be possible to catch the signal in a BPM process by listening to the signal notePostedInCaseBySupportManager.{$id}.

Example (object signal)

Workflow on Quote Item broadcasts a signal when amount is changed.

bpm\broadcastSignal('@quoteItemIsChanged', 'Quote', entity\attribute('quoteId'));

Then it will be possible to catch the signal by a workflow. It can be useful for situations when you need to recalculate something when a related record is changed.
