Hi Praneeth,
PRT which is assigned in routing operation will display only short text. If long text exists for the PRT the long text check box which be cheked. If you click on that it will display the long text.
Upon creating of order PRT data gets copied to the operation data of the order. When you print the order, then PRT data against the order with PRT description gets printed. This will be information for the person who is working on the particular operation to know what is the PRT he is using.
Check in Config OPK8 LF01 -PRT Overview is checked or not. If it is checked then it will be printed. Try to explore if any possiblity to print long text.
You can use FM READ_TEXT to fetch the long Text.
Thanks & Regards,
Ramagiri
