PI mapping : particular value from a range of values and map it to a key.

Hi Gurus,

  I am facing one issue in one of my mapping. I have the below requirement

Range : if source value is in b/w

1) 600000 to 609999  Use the key value as VAKR

2) 900000 to 909999 use the key value as DITR.

Please help me out to build a logic for the above in PI.

Regards
