Hello,
ITS transactions are not relevant in SRM 7.0 anymore.
Shopping cart check status is replaced by POWL. Cart creator can see his documents in POWL.
Monitor shopping cart will be available to SRM administrator (GUI role /SAPSRM/ADMINISTRATOR - portal role com.sap.pct.srm.core.ro_srmadministrator.
Check note 1261825 to see the correct roles (GUI and portal) to be assigned to end users.
Regards,
Ricardo
