I want to taken online reading of equipment e.g temperature of PLC in to SAP data base. and if its lower or upper limit range of temperature reached a planned notification will create. I am going to use measuring point for this with user exit IMRC0001.
Now My query is how to update reading in measurement document.??? if for every change in reading if I create one document then there will be too many document for only one parameter.
and if I update reading in regular time period lets after every 4 hrs then in that case my last reading will be recorded in system . In between this 4 hr if my temp cross my limit and again come down then that condition will not record in system .
If any one come across to this situation please guide me .
