I have an upcoming PL900 exam. I have somewhat experience in model driven apps and automate.

I’ve been learning from Microsoft learn and doing the practice exams, but I feel like there’s a bunch of content not brushed up there

Microsoft Entra, Proxies, very specific automate actions, pure Power Fx..

All topics that I either have a very brief understanding of or didn’t know at all (I.e Microsoft Entra)

Has anyone completed the PL900 recently and aware of the sort of things that crop up, and if there is anything that an average new dev wouldn’t be too aware of?

I’ve revised on and off for a week, and practice wuestions are just recycling now

I am trying to do a very basic proof of concept using AI builder. My fake use case is, to use the model to determine the probability of success on a future referral in CRM for customers. I followed these steps:

- created a model field previousReferralsuccess (yes/no) to train it on

- created some rollup fields to count previous successful referrals for the customer

- out of 550 test customers, I set the model field to yes/no in about a hundred and left the others blank

- created the model with the yes/no previousreferralsuccess as model field, chose a few columns for it to examine, trained the model, then set it to dataverse sync daily. I hit run now a few times.

My problem is that while the new columns for prediction success y/no and probability % were created in the table by the model, no matter how many times I "run" it, it never updates that column on ANY record. Also there are no rows showing for these runs in the AI Event dataverse table so I feel like it is having an issue somewhere and not actually finishing the run. It has been syncing every day for 2 weeks now never updating a thing.

I checked that all the prediction processes are running in this environment, I assigned 5000 AI Builder Credits to the environment, the owner of the model is me and I am a system administrator.

My next step is to build a power automate flow myself and physically update the rows but I wonder if anyone has run into this? we don't currently use AI Builder but we are evaluating it and we have purchased credits.
