Robot being called by click from Webpage

We are thinking to Automate Oracle, SAP ERP manual processes. Our intention is the Robot should be accessible from Web somewhere. That will be accessed by a mouse click with some input values. Then it will do an action on the ERP entity. Example: We have a sales Order in Oracle ERP. We want a specific hold to be applied. The WEB will accept the Order number and hold name and a click. Then the hold will be applied on the specific Order in ERP. Is it possible?

Any answer please?
