Early watch report is a alert report of customers SAP system given by SAP active global support after collecting systems data, contains (reports and solution note)  identified potential problems at an early stage, system bottlenakes, system performance and stability.

We create any object in Delopment and save it and we assain a request no for each object in develpment server.
First we we release the sap object Request no  from development using t-codes SE09, SE10 in Devlopment server.  After releasing we import request using T-code STMS. Where we find the released request no's and then selecting that request no we transport that request no to quality server by providing the client no.
After Transportation is finished the object is now in quality server where we can find the data in the database to test the object. Here we execute the object and check whether it is givint the right values in the output or not of going to dump. Testing here is noting but exeution of objects providing data for input and in database. If the output is showing correct as per requirement then the data is transported to Production server.
