Execute Modification Async (Batch)

Executes a modification asynchronously for multiple process instances. To execute a modification synchronously, use the Execute Modification method.

For more information about the difference between synchronous and asynchronous execution of a modification, please refer to the related section of the user guide.

Method

POST /modification/executeAsync

Parameters

Request Body

A JSON object with the following properties:

Name Description

processDefinitionId The id of the process definition for the modification

skipCustomListeners Skip execution listener invocation for activities that are started or ended as part of this request.

skipIoMappings Skip execution of input/output variable mappings for activities that are started or ended as part of this request.

processInstanceIds A list of process instance ids to modify.

processInstanceQuery A process instance query like the request body described by POST /process-instance .

instructions

A JSON array of modification instructions. The instructions are executed in the order they are in. An instruction may have the following properties:

Name	Description
type	Mandatory. One of the following values: `cancel`, `startBeforeActivity`, `startAfterActivity`, `startTransition`. A `startBeforeActivity` and `cancel` instructions request to enter a given activity. A `startAfterActivity` instruction requests to execute the single outgoing sequence flow of a given activity. A `startTransition` instruction requests to execute a specific sequence flow.
activityId	Can be used with instructions of types `startBeforeActivity`, `startAfterActivity`, and `cancel`. Specifies the activity the instruction targets.
transitionId	Can be used with instructions of type `startTransition`. Specifies the sequence flow to start.
cancelCurrentActiveActivityInstances	Can be used with instructions of type `cancel`. Prevents the deletion of new created activity instances.

annotation An arbitrary text annotation set by a user for auditing reasons.

Result

A JSON object corresponding to the Batch interface in the engine. Its properties are as follows:

Name	Value	Description
id	String	The id of the batch.
type	String	The type of the batch. See the User Guide for more information about batch types.
totalJobs	Number	The total jobs of a batch is the number of batch execution jobs required to complete the batch.
jobsCreated	Number	The number of batch execution jobs already created by the seed job.
batchJobsPerSeed	Number	The number of batch execution jobs created per seed job invocation. The batch seed job is invoked until it has created all batch execution jobs required by the batch (see `totalJobs` property).
invocationsPerBatchJob	Number	Every batch execution job invokes the command executed by the batch `invocationsPerBatchJob` times. E.g., for a process instance migration batch this specifies the number of process instances which are migrated per batch execution job.
seedJobDefinitionId	String	The job definition id for the seed jobs of this batch.
monitorJobDefinitionId	String	The job definition id for the monitor jobs of this batch.
batchJobDefinitionId	String	The job definition id for the batch execution jobs of this batch.
suspended	Boolean	Indicates whether this batch is suspended or not.
tenantId	String	The tenant id of the batch.
createUserId	String	The id of the user that created the batch.

Response codes

Code	Media type	Description
200	application/json	Request successful.
400	application/json	In case following parameters are missing: instructions, processDefinitionId, activityId or transitionId, processInstanceIds or processInstanceQuery, an exception of type `InvalidRequestException` is returned. See the Introduction for the error response format.
