Hi Experts,

Can any one please help me on below requirement.

I have multiple excels in the subfolder like below.

daily they will add one excel. From all these excels I have to load only latest excel means with max date excel need to load dynamically.

For example in the above all excels "Extract20180616" is the latest excel this one need to load if any other excel Extract20180617 is added then it will be the latest so Extract20180617  has to be load.

Please help me on this.

Thanks in advance

How about this?

Table:

Load FileName() as File_Name,

     Date(Date#(Right(FileName(),8),'YYYYMMDD'),'DD/MM/YYYY') as DateField

From Extract*.xls;

Min_Max:

Load Max(DateField) as MaxDate,

     Min(DateField) as MinDate

Resident Table;

LET vMaxDate = Peek('MaxDate',0,'Min_Max');

Final:

Load * From Extract_$(vMaxDate).xls;

Before develop something, think If placed (The Right information | To the right people | At the Right time | In the Right place | With the Right context)

Hi Anil,

Thanks for your reply.

By making small changes its working fine.

Table:
Load FileName() as File_Name,
Date(mid(FileName(),8,8),'YYYYMMDD') as DateField,

  //  Date(Date#(mid(FileName(),8,8) ,'YYYYMMDD'),'YYYYMMDD') as DateField,
   *
FROM [lib://Extract/Extract*.csv]
(txt, codepage is 28591, embedded labels, delimiter is '\t', msq);

Min_Max:
Load Max(DateField) as MaxDate,
     Min(DateField) as MinDate
Resident Table;

LET vMaxDate = Peek('MaxDate',0,'Min_Max');

Drop table Table;
Final:
Load * 
FROM [lib://Extract/Extract$(vMaxDate).csv]
(txt, codepage is 28591, embedded labels, delimiter is '\t', msq);
