Can someone help me with this expression?

Hi guys,

i've a problem with the following query, in particular with this script:

If(WildMatch(ApplyMap('KEY_TO_BS_STS21',ApplyMap('DOUBLE_MAPPING',[@10:17],'n/a')),008), If([@4:9]=030357,'PS_RADIO','RADIO'),
If(WildMatch(ApplyMap('KEY_TO_BS_STS21',ApplyMap('DOUBLE_MAPPING',[@10:17],'n/a')),'011'), If([@4:9]=030357,'PS_LAB','LAB')))

as new_field

With these conditions, also the rows n°4 and n°19 it should be valued, respectively with "PS_RADIO" and "PS_LAB".

Why it don't work? It's a problem of data format, syntax (brackets) or something else?

Attached is a sample data file.

The strange thing is that if i insert a inline table, the query works perfectly (see another attached file).

The output that i want to obtain is the following: if the field BS_STS21 = 008 and if the field CODICE_PRESIDIO = 030357, the record must show PS_RADIO, instead RADIO; if the field BS_STS21 = 011 and if the field CODICE_PRESIDIO = 030357, the record must show PS_LAB, instead LAB. All the records must have a value in the column TIPO.

Please, someone could show me the right direction?

Thanks,

Mattia

Why there is 2 mapping table of the same column?

Which field should mapped with if there is 2 identical match? eg: 04111 and 05111

KEY_TO_NOTA:
Mapping LOAD * INLINE [
FIELD3, FIELD4
0443, -
0529, -
3869, -
04111, IHca
06111, -
05111, Ihmac
0442, -
0441, -
0440, -
];

KEY_TO_BS_STS21:
Mapping LOAD * INLINE [
FIELD3, FIELD4
0443, 021
0529, 008
3869, 008
04111, 021
06111, 011
05111, 021
0442, 011
0441, 021
0440, 021
];

In your Actual sample, i dont see this issue:

KEY_TO_NOTA:
Mapping LOAD
CODICE_PRESTAZIONE,
NOTA

FROM
[C:\Users\Baronim\Desktop\2019_Tariffario_C.xlsx]
(ooxml, embedded labels, table is Tariffario);

KEY_TO_BS_STS21:
Mapping LOAD
CODICE_PRESTAZIONE,
BS_STS21

Can you please check again?

Hi Arthur,

i'm agree but the query that i need is in the other attachment.

I don't know why but this query (that is made by sample data) works perfectely, while the query i need don't work!

I'm sorry Arthur, i don't understand the problem.

The only query that i need is in the QV named Sample_data_P.

Buonasera Mattia,

il problema sembra nascere dal fatto che per ciascun CONTATORE_PRESCRIZIONE ci sono più CODICE_PRESTAZIONE. Di conseguenza il mapping prende uno dei tanti valori possibili.

Per risolvere bisogna usare la giusta chiave nel mapping, in modo che il collegamento sia 1:1

Grazie mille per il suggerimento!

In realtà ho già risolto utilizzando la funzione Left Join mettendo da parte ApplyMap che non mi dava il risultato desiderato.
