ChaRM preceding document status does not change

Hello Experts,

We have configured ChaRM 7.1 SP08 and as per requirement the successor change document for an Incident (SMIN) is an Urgent change (SMHF) document. So when the status of Urgent change document changes, the respective Incident status should be set automatically. We have maintained the entries for SMHF in SPRO "Specify status settings for predecessor documents", but the status of SMIN doesn't change. We even tried maitaining entries for SMIN "Specify Required Status Values for Successor", doesn't seem to work either way.

Any help in this regard will be much appreciated.

Thanks & Regards,

Sameer
