As mentioned above, tender groups allow users to collect planned items which they plan to submit in a tender. However, this does not have to be the case as a tender group may result in several tenders and purchases. Users can make use of main groups and sub-groups to create the groups they want. Users can also create as many levels of main groups and sub-groups as they want. items must either be linked to a tender group if this does not have sub-groups or to the lowest level of a sub-group.
