We have this issue when using CHARM in Solman 7.1 to import transports for Urgent Change documents (ZMHF).
When we import 2 transports (1 released Workbench and 1 unreleased empty transport) to the ECC QA system, the system returned with error "Not all transports yet released". The Task List log displyed that releasing process was completed ok, but the import process was not started.
We had this issue after we applied Support Pack (EHP6) to our ECC QA system.
Prior to the upgrade, the releasing and import process are ok even there is empty transport. The system will just delete the empty transport when we use the action "Pass Urgent Change to Test".
Has anyone have any idea about this issue?
