Get column value for specific columns

Question

I want to change the default behavior of a IKM. In a specific step, I need to call a PLSQL procedure inside the loop below, and that procedure will substitute the insert clause. The procedure uses only some attributes, and I need to check the name of each one when I use the getColList method.
     for aRecord in myCursor loop
          insert into      <%=snpRef.getTable("L","TARG_NAME","A")%>
               <%=snpRef.getColList("", "[COL_NAME]", ",\n\t\t\t", "", "((INS AND (NOT TRG)) AND REW)")%>
               <%=snpRef.getColList(",", "[COL_NAME]", ",\n\t\t\t", "", "((INS AND TRG) AND REW)")%>
          values
               <%=snpRef.getColList("", "aRecord.[COL_NAME]", ", \n\t\t\t", "", "((INS AND (NOT TRG)) AND REW)")%>
               <%=snpRef.getColList(",", "aRecord.[COL_NAME]", ", \n\t\t\t", "", "((INS AND TRG) AND REW)")%>
     end loop;
For example, to call the procedure I do that: schema.proc_1(col1, col2, col3). However, I have more than 3 columns, and I need to restrict them when I use the getColList method. I would like to know if there is a way to get only specific columns, giving these names. I pass the name of the column, and the method should return its value. Can I use the getColList to do that? Is there any other way to do that?

Hi Luciene,
You can use the UD flags to do this. If you click on one of your mappings in the Diagram tab of your interface you will notice several UD flags (UD1 to UD5) you can use those to flag the columns you want to use in proc_1.
To summarize:
- at the interface level flag the columns you want to use in your PL/SQL code -> check UD1 for all of them
- modify your IKM code:
<%=odiRef.getColList(",", "COL_NAME", ",\n\t\t\t", "", "((INS AND TRG) AND REW AND UD1)")%> <- retrieve columns flagged with insert, not read only, mapped on target and with UD1 flagged. The "AND UD1" part can be used in other getColList.
Hope this helps.
Thanks,
