Dynamic Field assignment through context variabla

[Anonymous]

Hi!

I am looking for a solution for below scenario : 

file as below : 

field1,field2,field3

1,2,3

4,5,6

7,8,9

i want an output file like below : 

field4,field5,field6 -- these are column headers and in tmap i want to write something like 

row1.context.variable ---context variable is given while manually running the job.

Basically i want to give mapping dynamically .

field1 is mapped to field4 sometimes , field 1 is mapped to field 5 sometimes ,  mapping information is given in another file .

mapping file will have source and target values like below 

source,target

filed1,field4

field2,field5

field3,field6 

mapping file values are stored in context variables.

Mapping file values change each time and in tmap i should be able to map based on context variables.

i am able to assign context variable values from the file but the part where mapping is done dynamically i am struggling.

Please help .

Thanks in Advance,

Alekya
