The Update-Approval-Limits-Request is used to supply (populate) Unimarket with approval chain information from an external system. This integration point is used when a Community has existing approval structures in an external system such as their FMIS/ERP that they want to replicate in Unimarket in an automated way. The update is typically triggered on a periodic basis such as once every night to ensure Unimarket and the external system are in sync. It contains heirarchical approval 'chains' including approvers and their approval limits ($).
