For more information about creating activities, see [Creating a Pega activity](/flexi-capture/connectors/pega/pega-activity-create). ## Pages & 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 | ## Steps Step 1: **Method**: Obj-Open-By-Handle. **Step page**: Case. **InstanceHandle**: Param.CaseId.

If such a condition does not already exist, window will open where you will be able to create a new condition. Make sure that the full name of the case is specified in the **Apply to** field and click **Create and open**. On the **Conditions** tab, create the following condition: *length of .pyAttachments is Equal To 0*. To add the condition, click **Configure advanced conditions here…** and select the *length of \[a pagelist property] Is \[comparison operator] \[value]* for the condition type. Screenshot of the Condition dialog in Pega defining the AttachmentsIsNull condition as length of .pyAttachments Is Equal To 0. **Jump**: | **When** | **if true** | **true param** | **if false** | **false param** | | -------- | ------------- | -------------- | ------------ | --------------- | | true | Exit Activity | | | | 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. Screenshot of the When conditions dialog in Pega for step 2, with the AttachmentsIsNull condition set to Continue Whens if true and Skip Step if false. Screenshot of the Jump conditions for step 2 in Pega, with a When value of true that exits the activity.

Screenshot of step 3 in Pega using the Call-Function method, with the function @ABBYY.CreateNewBatch() and a return value of Local.BatchId. 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. Step 4: **Method**: Property-Set | **PropertiesName** | **PropertiesValue** | | ------------------ | -------------------------------------------- | | Local.LinkedRefTo | Case.pyAttachments(\).pxLinkedRefTo | | Local.Id | Case.pyAttachments(\).pzInsKey | **Loop**: | **Repeat** | **Value List Property** | | ------------------------------ | ----------------------- | | For each element in value list | Case.pyAttachments | 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. 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. Substep 1: **Method**: Obj-Open-By-Handle. **Step page**: Attachment. **InstanceHandle**: Local.LinkedRefTo.

Screenshot of substep 3 in Pega using the Call-Function method, with the function @ABBYY.AddDocumentToBatch(Local.BatchId, AttachmentInfo.pyMemo, Attachment.pyAttachStream) and no return value. Screenshot of the Jump conditions for substep 3 in Pega, with a StepStatusFail condition that jumps to later step ERR if true and an on-exception label of ERR. Step 5: **Method**: Call-Function | **Function** | **Return value** | | ---------------------------------------- | ---------------- | | @ABBYY.RunBatchProcessing(Local.BatchId) | | For more information, see [RunBatchProcessing](/flexi-capture/connectors/pega/pega-func-multiple-docs#runbatchprocessing). **Jump**: | **When** | **if true** | **true param** | **if false** | **false param** | | -------------- | ------------------ | -------------- | ------------ | --------------- | | StepStatusFail | Jump to Later Step | ERR | | | **On exception, jump to later step label**: ERR. Screenshot of step 5 in Pega using the Call-Function method, with the function @ABBYY.RunBatchProcessing(Local.BatchId) and no return value. Screenshot of the Jump conditions for step 5 in Pega, with a StepStatusFail condition that jumps to later step ERR if true and an on-exception label of ERR.
