Anybody tried to create a flow, which will take a backup of existing package and put it in a specific folder. The idea is to automate the backup process whenever a new version of that package needs to be installed on the production. When I opened that dsp page (wmRoot/package-release-selection.dsp) it seems they are using wm.server.replicator:packageUnrelease but I don’t know how to find some documentation for these services. Advanced Business partner Integration for Developers guide just gives idea about how to get the invoked service not the documentation about the service. We are using B2B 4.0.2 thats the reason we want to build this service.
