Date format change in qlik?

[#1]

Hi community,

     I have date column in my csv file in two formats,

1.format = mm/dd/yyyy

2.number format= 41730,

monthname(Date(alt("Inv Date", Date(Date#("Inv Date", 'MM/DD/YYYY'), 'MMM-YYYY'),

Date(num("Inv Date"), 'MMM-YYYY') ))) as "Invoice Date" ,

used above script to change the format,

when i am trying to change the format to mmm-yyyy, system is getting confused to take some records

for example : 10/01/2015(oct 1st 2015) but it is loading as Jan 2015(Jan 10th 2015).

And am not sure how the number format is changing.

Please help me how can I resolve this.

This should work for you:

Date(Date#([Inv date], 'MM/DD/YYYY'), 'MMM-YYYY') as [Expected Output]
