“world domination” is the dangling carrot 🥕
Endless amounts of money will be pumped into this bubble. No one wants to be on the loosing side. It might not burst until someone wins. 💨

I like these, too. But how do we get SAP to do better? This is a good example where “the answer was in the system”. It would have been really nice if the dump was not 23 pages of irrelevant data but simply said, “your internal table includes field xyz which is not present in the db table”

An “indefinite license” isn’t worth much when updates stop after a year. Who wants a security bug in a file explorer? Value at that time = 0.

Processing large itabs can be a fun challenge. Important is keeping it at O(n) meaning a single loop over the data. Assigning field-symbol is generally the fastest, nothing changed.
More important is to measure first, then optimize rather than guessing what might slow things down.

Anything less would be disappointing after taking "the internet" down for several hours. I wonder the financial impact since they "advertise 100% uptime sla". that might be the biggest ouch

Detailed and honest post mortems are a great read and you can learn a lot from them.
Quite a few bad design decisions in this one. Your feature file (input) is too big and you let the system panic?

PS: LLM are trained on a lot of bad code as well. What many say are hallucinations are actually results of training on code that was never reviewed.
For example, LLMs love to change test scripts to auto update snapshots... because that's what devs do as well.

I had a model code its own sanitizeHtml. Dangerous!
I replaced it with a well known library that isn't going to compromise my system. Too many eyes on it. Also much more future proof since it's easy to update if new security issues are discovered and fixes become available.

One should study how much ABAP - customer or SAP - is just shuffling data from one format to another. 50%?

So many think “cloud” is easy. This shows nicely what’s really involved: it’s a long journey with lots of pain in between

Sadly, the community moved from SCN to LinkedIn. A few kudos here vs thousands of likes there for the same announcement. This is the result of @sapcommunity.bsky.social own doing.
At least there’s something to discuss although it’s mostly announcements that we can’t try yet.

Some are doing the right thing but all it takes is a few bad apples.
“The People” have no comprehension of how much just one billion is:
That $10,000 spend every day for 274 years.
It came from the People and taxes need to get it back.
