" IF 1 = 2 ", what make this condition sense here?

Hello Gurus,

I have a excerpt from function module used for sap bw extraction from generic datasource.

CASE i_dsource.

WHEN 'ZMOZ_DELTA_OPEW'.

WHEN OTHERS. IF 1 = 2. MESSAGE e009(r3). ENDIF.

for " IF 1 = 2. MESSAGE e009(r3). ENDIF", condition "IF 1 = 2" is always false, so I suppose statement after this condition will not be excuted, so what does this conditional statement really mean putting here?

Many thanks
