SendForProcessing activity for a single-document case

Configure the SendForProcessing Pega activity for a single-document case: open the case, loop over the attachments, and call ABBYY FlexiCapture to start processing.

The SendForProcessing activity opens the case, sends the first attachment to ABBYY FlexiCapture, and stores the batch identifier and the verification URL that FlexiCapture returns.

For the general procedure, see Create a Pega activity.

Activity steps

1. Open the case

   Field	Value
   Method	Obj-Open-By-Handle
   Step page	Case
   InstanceHandle	Param.CaseId

   
2. Reset the attachment counter

   Set Method to Property-Set and the property as follows:

   PropertiesName	PropertiesValue
   Local.Index	0

   
3. Loop over the case attachments

   Set Method to Property-Set and the properties as follows:

   PropertiesName	PropertiesValue
   Local.LinkedRefTo	Case.pyAttachments(<CURRENT>).pxLinkedRefTo
   Local.Id	Case.pyAttachments(<CURRENT>).pzInsKey

   

   Set the Loop properties as follows:

   Repeat	Value List Property
   For each element in value list	Case.pyAttachments

   

   Add the following When condition, so that only the first attachment is sent:

   When	if true	true param	if false	false param
   Local.Index==0	Continue Whens		Skip Step

   

   Add the following substeps to this step, so that the loop repeats them for each attachment:

   1. Open the attachment

      Field	Value
      Method	Obj-Open-By-Handle
      Step page	Attachment
      InstanceHandle	Local.LinkedRefTo

      

   2. Open the attachment information

      Field	Value
      Method	Obj-Open-By-Handle
      Step page	AttachmentInfo
      InstanceHandle	Local.Id

      

   3. Send the document to ABBYY FlexiCapture

      Set Method to Call-Function and the function as follows:

      Function	Return value
      @ABBYY.SendForProcessing(AttachmentInfo.pyMemo, Attachment.pyAttachStream)	.BatchId

      For more information, see SendForProcessing.

      Add the following Jump condition, and set On exception, jump to later step label to ERR:

      When	if true	true param	if false	false param
      StepStatusFail	Jump to Later Step	ERR

      
      

   4. Wait for the verification URL

      Set Method to Call-Function and the function as follows:

      Function	Return value
      @ABBYY.WaitFirstVerificationOrProcessed(.BatchId)	.VerificationUrl

      For more information, see WaitFirstVerificationOrProcessed.

      Add the following Jump condition, and set On exception, jump to later step label to ERR:

      When	if true	true param	if false	false param
      StepStatusFail	Jump to Later Step	ERR	Jump to Later Step	INC

      
      

   5. Post the error message

      Field	Value
      Label	ERR
      Method	Page-Set-Messages
      Message	@unescapeHTML(@getWorstMessageName(tools))

      For more information, see unescapeHTML.

      Add the following Jump condition:

      When	if true	true param	if false	false param
      true	Exit Activity

      
      

   6. Increment the attachment counter

      Set Label to INC, set Method to Property-Set, and set the property as follows:

      PropertiesName	PropertiesValue
      Local.Index	Local.Index + 1
