AMDP internal table move corresponding

Hello,

In AMDP, is there a way to move data from itab1 to itab2 for the below structure.

itab1 = Field1, Field2, Field3

itab2 = Field1, Field2

itab1 has an extra field which is not available in itab2.

I am in a situation to use only select * as the number of fields are huge so explicitly mentioning the field name is not an option here.

Appreciate if you can share some thoughts.

Thanks.
