Following the resolution included in the KBA 1707688 (Customized Request for Change transaction cannot be confirmed), I recently was able to resolve the issue whereby the ZMCR remained in status Being Implemented after the ZMMJ had been Imported to Production.
Since then I have made some configuration changes (transport request import strategy) so that the transport request cannot be imported to production until the ZMMJ status is Released for Import (E0014). Without that configuration the transport request can be imported to production once the ZMMJ status is Successfully Tested (E0009).
Unfortunately, now the previous issue with ZMCR has reappeared: its status remains Being Implemented even after ZMMJ status is Imported to Production. Does anyone have suggestions on how to resolve this?
Here is the configuration that was done as part of the KBA.
