## Content

**Intro:** A good technical specification lets another developer build and test the object without a meeting. This template gives you the sections reviewers expect: objective, data model, selection screen, logic, error handling, authorisation, performance and test scenarios.

**Sections:**

#### How to use it

**Body:** Fill the fields in order, starting with the objective and the functional specification reference. List the tables and views the object reads, since that is where the review of performance and authorisation begins. Describe the selection screen with mandatory fields and defaults, then write the processing logic as numbered steps. Export to PDF for review or to Word for comments. Keep one specification per object and version it with the transport request.

**Bullets:**

- One specification per development object
- Link to the functional specification by ID
- Number the logic steps so reviewers can comment on them

#### What reviewers look for

**Body:** Reviewers check that the data model matches the real tables and that the volume is stated, because performance problems start with a missing volume. They look at authorisation: which object protects the data, and what happens when a user lacks it. They check error handling for missing master data and empty results, and for interfaces, what happens on a retry. A specification that says how failures are handled usually produces fewer production incidents.

**Bullets:**

- State expected data volumes
- Name the authorisation object and fields checked
- Describe empty result and error cases
- For interfaces, describe retry and duplicate handling

#### Tips for stronger specs

**Body:** Write in the language of the data: use real table and field names, not descriptions. Include a small worked example with input values and the expected output row, since an example removes most ambiguity. Record decisions, for example why a CDS view was chosen over a report, so later maintainers understand the reasoning. Keep the document short. If it needs thirty pages, the object probably needs splitting.

**Bullets:**

- Use real table and field names
- Include a worked example row
- Record design decisions and alternatives
- Keep it short enough to read in one sitting

**Cta:** Netray can help turn functional specs into reviewed technical designs and draft code inside your own environment, with developers approving every change.

**Faq:**

#### What is the difference between a functional and a technical specification?

**Answer:** The functional specification states what the business needs and the rules. The technical specification states how the object will be built: tables, logic, authorisations, error handling and tests. Developers write or complete the second from the first.

#### How long should an ABAP technical specification be?

**Answer:** For a report or enhancement, two to five pages is typical. Interfaces and conversions may need more because of field mappings. Use a separate mapping table rather than long prose.

#### Should the spec include code?

**Answer:** Short pseudo-code or key queries can help, but the specification should not duplicate the program. Put the logic in steps and let the code be the implementation.

#### Who signs off the technical specification?

**Answer:** Usually the functional consultant, a technical lead and sometimes the business owner. Agree this in the project before the first object is specified.
