The `SendForProcessing` activity creates a batch in ABBYY FlexiCapture, adds every case attachment to it, starts processing, and stores the batch identifier on the case. For the general procedure, see [Create a Pega activity](/flexi-capture/connectors/pega/pega-activity-create). ## Pages and classes | Page name | Class | | ---------------- | ---------------------- | | `Case` | `Work-` | | `Attachment` | `Data-WorkAttach-File` | | `AttachmentInfo` | `Data-WorkAttach-File` | ## Parameters | Name | Data type | Required | | -------- | --------- | -------- | | `CaseId` | `String` | Yes | ## Local variables | Name | Data type | | ------------- | --------- | | `LinkedRefTo` | `String` | | `Id` | `String` | | `BatchId` | `String` | ## Activity steps | Field | Value | | ------------------ | -------------------- | | **Method** | `Obj-Open-By-Handle` | | **Step page** | `Case` | | **InstanceHandle** | `Param.CaseId` | Screenshot of step 1 in Pega configured with the Obj-Open-By-Handle method, the Case step page, and an InstanceHandle of Param.CaseId. | Field | Value | | ----------- | --------------------------------------------- | | **Method** | `Page-Set-Messages` | | **Message** | `Please add files to case before proceeding.` | Screenshot of step 2 in Pega using the Page-Set-Messages method, with the Message set to the text prompting the user to add files to the case before proceeding. Add the following **When** condition: | When | if true | true param | if false | false param | | ------------------- | -------------- | ---------- | --------- | ----------- | | `AttachmentsIsNull` | Continue Whens | | Skip Step | | To build the `AttachmentsIsNull` condition: 1. In the **When** field, specify `AttachmentsIsNull` and click the configuration button. If the condition does not exist yet, a window opens in which you can create it. 2. Make sure that the full name of the case is specified in the **Apply to** field, and then click **Create and open**. 3. On the **Conditions** tab, click **Configure advanced conditions here** and select the `length of [a pagelist property] Is [comparison operator] [value]` condition type. 4. Create the condition `length of .pyAttachments is Equal To 0`. Screenshot of the Condition dialog in Pega defining the AttachmentsIsNull condition as length of .pyAttachments Is Equal To 0.

Screenshot of the Jump conditions for step 3 in Pega, with a StepStatusFail condition that jumps to later step ERR if true and an on-exception label of ERR. Set **Method** to `Property-Set` and the properties as follows: | PropertiesName | PropertiesValue | | ------------------- | --------------------------------------------- | | `Local.LinkedRefTo` | `Case.pyAttachments().pxLinkedRefTo` | | `Local.Id` | `Case.pyAttachments().pzInsKey` | Screenshot of step 4 in Pega using the Property-Set method, with Local.LinkedRefTo set to the pxLinkedRefTo of the current Case.pyAttachments element and Local.Id set to its pzInsKey. Set the **Loop** properties as follows: | Repeat | Value List Property | | ------------------------------ | -------------------- | | For each element in value list | `Case.pyAttachments` | Screenshot of the Loop dialog in Pega for step 4, with Repeat set to For each element in value list and the Value List Property set to Case.pyAttachments.
