    The points to be included in technical specs are:

    Business Requirement

    From business standpoint describe:

    Objective - What the object(s) are supposed to accomplish?

    Purpose - Describe what are the purposes of these object(s)?

    Users - Describe who will use are these object(s)? And when? And where?

    Known Errors / Issues - Describe any known errors and issues

    TS template are client specific.

    Ask any seniour person from ur project to provide template used for TS .

    In that TS u have to provide details such as developer, tester, std tables used, Internal tables, Process flow etc.
