Hi this is actually my 2 loads. the 2nd table is actually loading many other different column from the first table. I just want to use the newly created column in my 2nd table. But this is giving error because they say NEWCOLUMN cannot be found from the 2nd load. How do I fix this?

If 20161231.xls doesn't include NEWCOLUMN, you cannot use this field in your load without bringing this from your BOS_MAPPING table without joining the two tables or using Lookup or ApplyMap. The field needs to be in the load of a table before you can use it for any calculations.

Best,
