Problem: After importing a COBOL program for use as a LINK with Channel node, and opening the operation in the operations editor, you cannot modify the generation properties to select Service Flow runtime: level 1.0 is not listed as a choice for selection.
Workaround: Change the program type to commarea or MQ, press OK, save your changes, then reopen the generation properties editor. Then the choice for runtime level 1.0 is available.
