Hi,
I believe that the problem you are having is that you have a delimited file, of which you want to pick columns from position 2,3,5. In this case, ODI will pick the first 3 columns of a delimited file regardless of position.
For example, if you a tab delimited file with c1,c2,c3,c4,c5 columns, and you want only columns c2,c3,c5 - when mapping these in an ODI interface, and executing, you will actually pick up the data from c1,c2,c3 as these are the first three columns in the file (reading from left to right). You can ignore "columns" on the right hand side of a file, but not the left. E.g delimited file with c1,c2,c3,c4,c5. Only pick columns c1,c2 will give you data for the first 2 columns
Create a temporary table to load all the data from the file, and use you temp table to extract the data you require. Or you could get the file created with the first three columns as the columns you require.
