Hello. (picture from sandbox, i did not implement this, but trying to copy it.) I created a custom record "WPS ITEM (routing)" Which i want to add to a subtab inside another custom record, so that you can create new WPS ITEM (routing) and fullfill the lines on the WPS (manufacturing routing) I have tried to do it inside customization --> sub-tabs But that does not seem right. Does anybody know how to do this
