Creating a comparison extra field for my table

So, i have this table that I need to compare column "Food_name", and "Replacement for"

What I need:

everytime I pick one item from the field "Replacement for", it returns to me the item_id from the Food_name related to, and i want that to be stored as a field... For example:

If I pick any of the items that is a replacement for hamburguer, it should return to me the id = 1... So, If I choose fish, which is a replacement for hamburguer, it returns me the item_id 1...

The table is this one:

item_idFood_nameFood_PriceClassificationReplacement for
1hamburguer10unhealthy
2ice cream11unhealthy
3steak12unhealthy
4bread13healthy
5coke14unhealthy

The final table I would like to have it's this one, with that "item_id_Replacement" added created by qlikview :

Julio,

I think you can use Applymap() function.

First, load a table with two fields (Food_Name, id): first field is the key, second field is the one that will be the replacement

MapFood:

Mapping LOAD

Food_Name, item_id

....

And afterwars, use Applymap():

LOAD ...

Applymap('MapFood', Replacement_for) as newid,

.....

MapFood is a temp table. No need to drop it at the end of the script.

Right below expression in List Box Expression instead of selecting [Replacement for] directly...

=IF(Len([Replacement for])>0,[Replacement for])
