2772526 - You Can Not Upload an Attachment to Sales Order via Web Service due the Error "Update not possible; specified data for CUSTOMER_ORDER-ATTACHMENT_FOLDER does not exist"

You are trying to upload attachments to sales order with the web service "CustomerOrderProcessingManageCustomerOrderIn", but you're receiving the error message "Update not possible; specified data for CUSTOMER_ORDER-ATTACHMENT_FOLDER does not exist" in the response payload.

SAP Cloud for Customer

In the payload ActionCode 06 has been used in the payload's tag "<AttachmentFolder DocumentListCompleteTransmissionIndicator="false" ActionCode="06">".

The error appears as the action code 06 stands for no change.

Since the ActionCode 06 stands for no change, you should use the ActionCode 01 to create attachment documents.

You should use the ActionCode 01 as follows in the below payload's tag.

<AttachmentFolder DocumentListCompleteTransmissionIndicator="false" ActionCode="01">.

OBS: Before triggering the payload please check if the attachment node is already created or its a fresh entry.

This can be verified using the web service "CustomerOrderProcessingQueryCustomerOrderIn".
 
As the attachment is already available, the action code "01" will give the message as "Instance with the same key".
 
ActionCode = 01 : For first attachment (Along with the attachment file, the node instance is getting created).
ActionCode = 06: If you are adding further attachment file.
