Load sales month script

[josemaria_cabre]

Hi everyone,

I wrote this code to load different sales files by month:

FOR i = 1 to 12

    // Generate file name based on month
    LET vMonth = Pick(i,
        'january', 'february', 'march', 'april', 'may', 'june',
        'july', 'august', 'september', 'october', 'november', 'december'
        );
    
    trace $(i);
    trace $(vMonth);
    // File path 
    LET vFile = 'lib://MyData/sales_' & vMonth & '.csv';
    trace $(vFile);
    // Load data from file
    Sales:
    LOAD
        Date,
        Product,
        Amount,
        Price
         FROM [$(vFile)]
(txt, utf8, embedded labels, delimiter is ';', msq);

NEXT i

If I only have 2 files (e.g "sales_january.csv" and "sales_february.csv") in MyData directory, I get a "Cannot open file 'lib://MyData/sales_march.csv' error.

How can I load only existing files without getting this error?

Thanks in advance for your help,
Jose

Check if File exists 

IF FileSize($(vFile)) > 0 Then 

Sales:

Load *

From [$(vFile)]

End IF
