Answer Posted / nitin
1) Src-->SQ->Normalizer-->Target
The first pipeline breaks the rows and convert to columns and then write to target file.
1|A
1|B
1|C
1|D
2|A
2|B
3|A
3|B
2)Src->SQ->Exp->Target
The second pipeline receives the above output with '|' as delimiter and passes to expression.
In the expression transformation concatenate the second column with + for the same first column and then write to target with | as delimiter
