Hi Jagdeep, thanks for your answer, the problem is that we create the notification in the tx IQS1, if i run the tx IW52 with the notification number created in the tx IQS1 i get the following error:
in this moment we dont have any form to realice the relation between the notification created in the tx IQS1 with the Sales Order. We have to use excel and manually realice the relation but we cannot find the relation in SAP
