Process Chain Bug

Hello experts,

Perhaps this subject was already treated, I canu2019 find any answer in SDN, for this reason I am posting my question here.

I have an issue with a process chain, when I launch it, I see the job in transaction SM37, it is reported like finished.

When, I see the logs of the process chain in transaction RSPC, it is reported like always running (with yellow color...).

Few hours ago, When, I try to launch it a new time, I have a message (PC still running from last run)

How can I fix it please?

Many Thanks.

Best regards.

Amine
