I am facing an issue, ie., In schema_in I have column called "VKEY". in schema_out I'm having VKEY column(directly mapped from schema_in) also have another column called GEN_ROW. Mapping of this GEN_ROW column is( gen_row_num_by_group(VKEY)).
While validating I am getting an error called "column VKEY is not found". If I commented this GEN_ROW column mapping, I am not getting any error.
Kindly assist here, Thanks in advance.
