The KEL generated ECL codes (https://github.com/hpcc-systems/KEL/issues/2069) failed to run and reported error: "Error: INTENAL: Dataset is not active: 'right' (271,14 -...).
The bwr_kel2069 is the simplified ecl codes. I was able to get the dataset “_EE285” successfully. However I got the ecl error for “EE493”. The “EE493” is a joined dataset using the dataset “_EE285”.
