Dear Prathap,

Answer Scenario 1: No-matter either you are writing the same name in applymap or not which exist in Mapping Table, but the value must be same through which Mapping apply. The output field will be 2nd name of Mapping and when you rename field where you are using ApplyMap.

Answer Scenario 2: Please use field name for multiple values matching.

For more detail, kindly find attached sample.

Kind regards,

May be this

ExceptionFieldNameMaping:

MAPPING LOAD

     CField,

     DisplayFieldLabel

FROM Tab;

Tab:

field 1,

field 2,

Apply map('ExceptionFieldNameMaping',CField)    as   Field name,

FROM Tab 2;

Ans1:

In mapping table there would be only two fields. The first field is matched against the input and the second field is mapped (output) based on the match from the first field. So the order of fields in mapping table matters, because qv is always going to compare the values from the first field, irrespective of it's name. So mentioning the name of fields in applymap is not necessary.

Ans2:

You can use the field value directly in the applymap, but in that case you would be able to mention one value only. Usually you would want all the values in the field to be mapped, so you use field name instead. That is, by mentioning the field name, you are actually mentioning the all field values.

Hope this helps.

Apply map('ExceptionFieldNameMaping',CField,'NA')    as   Field name,
