Try this

Table:
LOAD Hash128(COMPANY&'|'&SUB_COMPANY&'|'&REGION&'|'&YEAR) as Key,
	 *;
LOAD * INLINE [
    COMPANY, SUB_COMPANY, REGION, YEAR, RANK
    ABC, AB, X, 2017, 3
    ABC, AO, Y, 2014, 8
    ABC, AO, X, 2016, 4
    XYZ, AA, Q, 2015, 3
    PQR, 21, X, 2015, LAST
];

MinMax:
LOAD MinYear + IterNo() - 1 as YEAR
While MinYear + IterNo() - 1 <= MaxYear;
LOAD Min(YEAR) as MinYear,
	 Max(YEAR) as MaxYear
Resident Table;

Left Join (MinMax)
LOAD DISTINCT COMPANY,
	 SUB_COMPANY,
	 REGION
Resident Table;

Concatenate (Table)
LOAD COMPANY,
	 SUB_COMPANY,
	 REGION,
	 YEAR
Resident MinMax
Where not Exists(Key, Hash128(COMPANY&'|'&SUB_COMPANY&'|'&REGION&'|'&YEAR));

DROP Table MinMax;
