I got allocated to project in sap btp as an integration developer . Can I stay in it or can I learn something and move on??

As per your exp in IT, can you please say which is good to choose :)

Skill SAP BTP is very much in demand , you can learn the GenAi side of things in SAP BTP,
Once you have a good understanding ,you should quit your job and move to another company in the same SAP BTP. Nothing wrong in skill
