I am executing T-code: KOK5 with a variant .
The report for the internal order master data is being generated .
On the line item report screen
I select -Select all (top left icon of table)
Select report from pop-up (example 6L03 ) by double clicking
Error is received
Error message/#: Internal error occurred, code 2
Message no. KN026
Can you let me know how to rectify this error . Is some authorisation is missing or SAP note needs to be applied .
Thanks & Regards
