Career decision suggestions

Hey buddies,

I am into corporate from last 4.6 years. I had started my career as a SAP MM consultant, I worked in my first project as a sap mm tester but while the project was over I got a project based on some other application i.e Maximo but there also they gave me the role as a tester , as it went well after it got over I again got a similar maximo project only. I wasn't given any SAP project, neither I was into testing also.

Now I want to switch my company, I am very eager to switch into SAP only but I have lost my touch with sap application, hands on and all. I can brush it up by doing some courses. Will this be good decision?

Any suggestions from you seniors can be helpful ☺️. Please guide me.
