Whilst this issue exists, users wishing to use the BMS Map editor will need to checkout the component to external, personal datasets and edit the components using RDz/IDz tools. Once complete the components can be checked back into the package for progression through the lifecycle.
No response is ever received and no errors appear on any log. In the customer's environment they receive a CMN6504I message but the member is created and appears to exist in the package. However, it cannot be edited in either ZMF4ECL or TSO/ISPF.
