Sorry it is hard for me to tell exactly because I cant read the errors.
I haven't done this with Dynamics and Oracle, but I have done flows similar with CosmoDB and MSSQL and various CRM's
I don't have a setup I make a test flow to see with Dynamics and Oracle, however piecing together from the translation on stack overflow you may have an issue with creating records without a unqiue index ( I had this issue with CosmoDB) as it throws an error as the record already exists.
There is a function you can use to make a GUID in Data Operators - Compose "@guid()" - Needs double quotes
This will create a globally unique ID you can use to solve an issue with creating records non indexed tables where the data may be the same.
