Hi Ricardo,
Here are some ideas as to how you could document your interfaces design and build:-
Firstly, during the design phase:
1. You could maintain a document for the overall picture-an architecture view...as to how many SAP and non-SAP systems, how they are talking to each other, etc. You should specify details about each system and what kind of data will each system be receiving/posting to XI, etc. How often is this data sent/rcvd, load details, etc.
2. Maintain another design document specific for each interface...with specific details about the data being loaded, validations being performed, mapping details,how the data is sent...which design approach..adapter details, etc; including the naming conventions being followed.
You can also maintain a separate document/embed a document with all the java codes that you might have probably used during mapping..to maintain clarity.
After the build and successful functioning of the interfaces, update the design documents.
During build phase, I don't think you will have to maintain any separate documents as such.
Btw, in Michal's FAQ blog, he has given the link to ASAP implementation approach. Do have a look at that too!
