Tables with function

Hey,

 

I need to build a table with xml files from an API.

 

 

 

(data as text) =>
let

SourceURL = "https://ws-mercado.ren.pt/MarketInfoService.asmx", //host provides this address. Url ends often with "wsdl"


options = [ #"Accept-Encoding"= "gzip,deflate",
            #"SOAPAction"="https://ws-mercado.ren.pt/GetInfoForTimeFrameByInfoType", 
            #"Content-Type"="text/xml;charset=UTF-8",
            #"Connection"="Keep-Alive"
          ],
Source = Xml.Tables(Web.Contents(SourceURL, 
    [Content=Text.ToBinary("
<soapenv:Envelope xmlns:soapenv=#(0022)http://schemas.xmlsoap.org/soap/envelope/#(0022) xmlns:ws=#(0022)https://ws-mercado.ren.pt#(0022)>
   <soapenv:Header/>
   <soapenv:Body>
      <ws:GetInfoForTimeFrameByInfoType>
         <!--Optional:-->
         <ws:EndDay>"&data&"</ws:EndDay>
         <ws:StartDay>"&data&"</ws:StartDay>
         <!--Optional:-->
         <ws:InfoType>"&process&"</ws:InfoType>
      </ws:GetInfoForTimeFrameByInfoType>
   </soapenv:Body>
</soapenv:Envelope>"), 
Headers=options])),
    #"Table Expandida" = Table.ExpandTableColumn(Source, "Table", {"Name", "Table"}, {"Name.1", "Table.1"}),
    #"Table.1 Expandida" = Table.ExpandTableColumn(#"Table Expandida", "Table.1", {"Name", "Table"}, {"Name.2", "Table"}),
    #"Table Expandida1" = Table.ExpandTableColumn(#"Table.1 Expandida", "Table", {"GetInfoForTimeFrameByInfoTypeResult"}, {"GetInfoForTimeFrameByInfoTypeResult"}),
    GetInfoForTimeFrameByInfoTypeResult = #"Table Expandida1"{0}[GetInfoForTimeFrameByInfoTypeResult],
    #"XML Analisado" = Xml.Tables(GetInfoForTimeFrameByInfoTypeResult),
    #"Table Expandida2" = Table.ExpandTableColumn(#"XML Analisado", "Table", {"Name", "Table"}, {"Name.1", "Table.1"}),
    #"Table.1 Expandida1" = Table.ExpandTableColumn(#"Table Expandida2", "Table.1", {"MARKETDAY", "PERIOD", "UTCDATE", "SETTLEUNIT", "IMBALANCE"}, {"MARKETDAY", "PERIOD", "UTCDATE", "SETTLEUNIT", "IMBALANCE"})
in
    #"Table.1 Expandida1"

 

 

 

 

 

let
    Origem = List.Dates (#date(2022,1,1), 365 * 1, #duration(1,0,0,0)),
    #"Convertido em Tabela" = Table.FromList(Origem, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Tipo Alterado" = Table.TransformColumnTypes(#"Convertido em Tabela",{{"Column1", type date}}),
    #"Linhas Filtradas" = Table.SelectRows(#"Tipo Alterado", each [Column1] <= Date.From(DateTime.LocalNow())),
    #"Tipo Alterado1" = Table.TransformColumnTypes(#"Linhas Filtradas",{{"Column1", type text}}),
    #"Personalizado Adicionado" = Table.AddColumn(#"Tipo Alterado1", "Personalizado", each Text.End([Column1],4) & "-" & Text.Start(Text.End([Column1],7),2) & "-" & Text.Start([Column1],2)),
    #"Colunas com Nome Mudado" = Table.RenameColumns(#"Personalizado Adicionado",{{"Personalizado", "Data"}}),
    #"Colunas Removidas" = Table.RemoveColumns(#"Colunas com Nome Mudado",{"Column1"}),
    #"Added Custom" = Table.AddColumn(#"Colunas Removidas", "XML Data", each getXML_web([Data])),
    #"XML Data Expandida" = Table.ExpandTableColumn(#"Added Custom", "XML Data", {"Name", "Name.1", "MARKETDAY", "PERIOD", "UTCDATE", "SETTLEUNIT", "IMBALANCE"}, {"Name", "Name.1", "MARKETDAY", "PERIOD", "UTCDATE", "SETTLEUNIT", "IMBALANCE"}),
    #"Colunas Removidas1" = Table.RemoveColumns(#"XML Data Expandida",{"Data", "Name", "Name.1", "UTCDATE"}),
    #"Tipo Alterado2" = Table.TransformColumnTypes(#"Colunas Removidas1",{{"MARKETDAY", type date}, {"PERIOD", Int64.Type}, {"SETTLEUNIT", type text}}),
    #"Linhas Filtradas1" = Table.SelectRows(#"Tipo Alterado2", each ([SETTLEUNIT] = "ALARES")),
    #"Valor Substituído" = Table.ReplaceValue(#"Linhas Filtradas1",".",",",Replacer.ReplaceText,{"IMBALANCE"}),
    #"Tipo Alterado3" = Table.TransformColumnTypes(#"Valor Substituído",{{"IMBALANCE", type number}})
in
    #"Tipo Alterado3"

 

 

So far, I've made it.

 

In order to optimize the code, I wanted to run the function and complete the table only on dates that do not yet have values.

 

What this best method? IF? Or ohter method?

Thank you.

I'm not sure I understand the question. Are you essentially wanting to do an incremental refresh?
