How much effort is roughly needed to get a central ATC system up and running?

Hi Folks,

we are in the planning stages to set up a central ATC system and I have already read through Olga Dolinskaja's neat and very helpful blog post series about how to go about this.

Apart from knowing what to do - which is covered in the blog posts - , I'd also like to get a better handle on the effort we'll have to expect to get this done and I would therefore appreciate any feedback from any of you who have already done this. Judging from the how-to blog posts, my guess is that it won't be much more than a "couple of days", but I'd like to narrow this down a bit more if possible.

I'd also appreciate any hints about potential snags in the process we are likely to encounter - if any.

The central system will be a new 7.52 Netweaver system and the initial satellite systems are on 7.50 with EHP8 but more satellites will most likely be added later.

Apart from the technical setup we'll obviously also need to make the developers aware of this and this could prove "interesting" and potentially somewhat timeconsuming because they are spread-out across the globe and sometimes are just contracted for specific projects (see my related thread for some background).

Thanks for any feedback you have!

Cheers

Baerbel

Here is a quick update:

As some of you have already noticed, I started a blog series a month ago about Setting up a central ATC-system. I'll use that series to try and document not just what we did but also how long it actually took to do the various steps and tasks. This is why I haven't yet closed this thread and why I'll leave it as un-answered and open for now.

Cheers

Baerbel

I haven't worked with a multi-system setup before, but a small advice I can offer is to communicate it well and introduce your checks gradually starting with one or two of the most critical ones. It can be a bit depressing if developers are suddenly faced with 200 ATC errors they need to fix.

Hi Mike,

yes, the potentially large number of ATC errors and how to deal with them is high on my list of priorities and one reason why we haven't yet rolled out blocking on transport release. One of the first steps we'll take is to get the baseline defined once we have the central ATC system up and running to avoid presenting the developer currently working on a program with all the lingering issues from earlier development.

We already have ATC-related information in our development guidelines and I'll also organise short workshops and a presentation in the run-up to going live with "block on transport release".

The reason I posted this question is that I'd like to get a better handle on the timeline I'll need to plan with - are we talking about hours, days or even weeks from getting the central ATC-system setup to have it running operationally.

Cheers

Here’s how I’d approach it: almost everything is a warning, just a few errors. You will have cases where old issues crop up in newly changed code. You could use the ATC exemption mechanism and decide whether those should be fixed or else add them to a list (as opposed to real exemptions). I have been involved in setting this type of organization up where we had a small outsourced team who just fixed these.

Once the process is running smoothly, you can start to switch more items from warning to error.

Hi Baerbel,

some weeks ago I configured the central ATC on a 7.52 sandbox system. It tooks some hours to apply all the needed OSS notes, that is all.

Currently we are doing some tests. We still have no experience in daily usage.

Best regard

Johannes

Hi Bärbel,

in theory it's really a matter of hours to setup a central ATC system. With political, technical and other issues it could be a larger project. Currently I'm trying to go live with our first large develoment system since half a year (one tiny one is already live). But we are already near the goal line, ATC is live but no check at transport release yet.

  • implementing the SAP notes
  • maybe setup and test new check variants (incl. abapOpenChecks)
  • setup exemptions (with substitutes), setup mails
  • setup RFC connections (trusted RFC or system user?)
  • Firewall rules
  • train the developers
  • communicate suggestions for improvements with Walldorf ;-)
  • ...

But in the end it's definitaly worth the effort
