What are the acceptable Sap methods/steps to change standard SAP/Abap code?

[Former Member]

To you Sap experts:

Can you point me to Sap document that lists the acceptable methods to follow when modifing SAP standard (abap code). We are on release 4..7.

I assume there is a best practice guide if you have to modify standard Sap code of what to do and don't do. Ex:. Field exit, CMOD, SMOD... Thanks for assistance.

Hi,

You can implement your own logic using User Exits (which includes function module exits, screen exits, field exits and menu exits), Badi's, Enhancement points and Business Transaction, Events.

Thanks,

Information helpful.

I was looking for a Sap guide that lists the acceptable methods and why you would pick one approach over another with consideration to long term maintenance and future upgrade of Sap systems.
