    The format of functional specifications varies by company.

    You need to either download the templates from your Solution Manager (or whatever solution you use to store this kind of documentation) or simply ask your colleagues to send you the current template versions.

    As to how you learn to write good specifications - start by reading the ones which the most experienced consultants in your company have written (if possible - find something that your solution architect has created).

    Another good approach is to ask the developers for feedback on the documentation which you provide, they can surely give you some good advice.

    It is maybe, the most difficult question

    You will never find a good answer because it depends a lot of the development team & about the subject. Some FS need a lot of details, some others need only high level explaination.

    Normally a FS is only the explaination of the Business Requirement, It should not indicate the technology, only what will be expected by the user & the functional rules.

    A TS is the technical realisation of an FS

    After a lot of discussions, the DS is really close to the end-user documentation with some explaination of the functionality (where to find objects, link, transaction ...) (never never gives Function Module, Class, Tables ...)

    And for me the most important is to list all the rules, gives a fixed name (never change) and a good title. After you could ask the development team to keep this rules names inside the code. And it will be easier to read & check the code.
