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
