When we try to use ‘FF’ to zoom into a function, we get kicked out with the message "Run-Unit ended at 3351 in YMSGACTE2I".
After upgrading 2E software release, customer retained the prior release libraries which was concatenated ahead of the new release libraries. To resolve, delete the prior release libraries or concatenated the current release libraries ahead of the prior release libraries. Found the cause after displaying the library YMSGACTE2I resided in.which was the prior release library.
It is good practice to check libraries by model after a software upgrade and retain the current release only. This avoids use of prior release libraries.
