SNOTE was a lifesaver when it came to note application and it doesn’t seem that long ago all SAP notes needed implementing manually including any code changes, table/fields creations etc.
The Note itself was pretty much the same as it is now, especially when viewed as a SAPScipt document. The note would still describe the symptoms, any pre-requisites; list all objects affected and describe the changes required but instead of being able to click the process button to implement the note (in most cases) you would have to go through every change to each object and add the code manually by modifying the SAP standard code yourself.
But now the majority of notes can be implemented via transaction SNOTE with the click of a few buttons. All the ABAP code instructions are then implemented onto your SAP system. Some things still need to be created manually but this list is reducing all the time and SAP can create most things for you now.
You may still have problems if you have made any modifications to SAP standard code but SNOTE offers you the split screen editor in these circumstances to help you apply the note correctly around your modifications.
