Writing new integrations in ABAP *on stack* in 2025 is a lot like inviting people over to your house
Should you do it? Can you do it? Sure. Absolutely even.
But if you let too much come and go - you could have a real mess

Lots of anguish about H1-B n the US
Big shakeups are undoubtedly coming to US - based SAP projects because of it
It is very common for 80-90 percent of SAP roles on US projects to be a past or present immigrants from India
Even common in US govt and defense roles where US Citizenship is reqd

Since earlier this year I’ve been tinkering again with blockchain/digital asset integrations with SAP
Initial results of the MVP/Poc I have are looking good.
Even if you typically write off the web3 domain you should find it interesting - particularly if you like cryptography
You will see soon!

Sometimes I wake up in the middle of the night from this nightmare from my past
It’s 2019 and the SAP S4 project I am on requires *every* REST API be created with SAP PI/PO
The EA banned oData services from consideration. Even the standard ones 😖😣

Randomly got some http 400 JSON serialization errors in a SAP CAP project this week
Double checked the payload and http handlers. No obvious flaws or issues
Updated all the node modules. Problem solved.
Not entirely sure why it worked - but I guess thats kudos to keeping apps up to date!

Here’s little issue I found with CAP and BTP destinations
If your destination has the property ‘HTML5.forwardAuthToken’ set to true - you are very likely to have issues using CAP’s native ‘cds.connect.to’
More cases than not - leave it off. Unless a specific oauth flow is mandatory

ABAP RAP and CAP Origin mythology
One day a pretty technical MD decided to build a little project in ABAP
All he wanted to do was to send a little POST body using a React frontend
After about 13 hours fiddling between ADT Eclipse crashing and SEGW doing bizarre things - things needed to change

2025 SAP BTP prediction
SAP’s Digital Currency Hub will have a bigger-than-ever presence at SAPPHIRE - as the incoming US admin is friendly to crypto
They will also debut a dog as their mascot!

One of the very simple reasons I now prefer CAP to building apps in ABAP is : cryptography
With CAP - you can easily integrate any kind of private keys for hashing, digitally signing, encrypting/decrypting, proving/verifying data
A big differentiator for building network-driven products in btp

I find it hilarious so many SAP influencers are speaking up so passionately AGAINST Hungarian notation so common in legacy ABAP code today
When I began my career in ABAP years ago - *not using* Hungarian notation as described by the TheHolyCompanyABAPStd2007.doc was grounds for public ridicule
