Dynamic Field assignment through context variabla

Anonymous — Thu, 23 May 2019 13:35:48 GMT

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
