EREC: Trex Errors in first run

Question

Hello,
We have EREC and HCM in two separate systems, i followed SAP note suggestions and created ALE connection to import the data. After i imported the data i ran HRLAXSYNC report in EREC system, which created NA objects.
Great, i was happy so far. Now i ran the TREX for the first time in production and see atleast few hundred if not more of similar errors as below, what did i do wrong? how can i fix this?

Hello Nicole,
The note has a prerequisite that erec is in integrated environment, but as mentioned above our EREC is not in integrated environment we are in I2-A scenario.
Please advise.
