Assuming that you are only interested in the effect put() has on the content of hashMap and don't care about the value it returns, the equivalent would be:

INSERT VALUE #( KEY = 'myKey' VALUE = 'myValue' ) INTO TABLE hashMap.

With the difference that for an existing key the entry will not be updated but SY-SUBRC will be set to 4, so you'd have to do some extra work. Internal table hashMap needs to be defined as a HASHED TABLE WITH UNIQUE KEY KEY and a type that has at least the fields KEY and VALUE.

Working example:

TYPES: BEGIN OF LINE,
    COL1,
    COL2,
  END OF LINE.

DATA:   WA TYPE LINE,
      ITAB TYPE HASHED TABLE OF LINE WITH UNIQUE KEY COL1.

WA-COL1 = 'X'. INSERT WA INTO TABLE ITAB.
WA-COL1 = 'Y'. INSERT WA INTO TABLE ITAB.
WA-COL1 = 'Y'. INSERT WA INTO TABLE ITAB. "Not added
