Because I have seen a lot of opinions regarding the extraction of the long texts from Notifications and Work orders, I suggest a very easy way.
When a long text exist in one Notification, you go to the text editor, GoTo-HEADER, and read the info from there:
Then enter SE37, Function Module READ_TEXT, and execute with the data from the Notification
Click on the 2 entries and you’ll get the Long text from the Notification.
For the Work Order the data that have to be provided in SE37 is:
You proceed the same way.
I hope this is useful.
