Hi Nick
I know you marked this answered. However I just wanted to add below details from SAP Note# 1686826 - Installation help for installing SCM Optimizers
Build date of SCM Optimizers: The build date provides information about the age of the SCM Optimizers used. To view the build date, call transaction RCC_VERSION (SCM 2007: RCCF_VERSION, before SCM 2007: /SAPAPO/OPT09). The column has the title "Created at". On SAP Service Marketplace, you can recognize the build date directly after the SCM Optimizer patch archive as the "Changed on" date.
Hope this will help.
Thank you
