This is Just an example of my requirement,

My requirement is :

Main:
LOAD * INLINE [

Values, Month, Year,Material_code
1, Oct, 2018, 2000001
2, Nov, 2018, 2000001
1, Dec, 2018, 2000001
1, Jan, 2019, 2000001
1, Feb, 2019, 2000001
1, Mar, 2019, 2000001
1, Apr, 2019, 2000001
5, May, 2019, 2000001
5, Jun, 2019, 2000001
5, Jul, 2019, 2000001
6, Oct, 2018, 2000002
9, Nov, 2018, 2000002
4, Dec, 2018, 2000002
4, Jan, 2019, 2000002
4, Feb, 2019, 2000002
4, Mar, 2019, 2000002
7, Apr, 2019, 2000002
7, May, 2019, 2000002
2, Jun, 2019, 2000002
2, Jul, 2019, 2000002
];

the Value of the Previous Month should be displayed in my next month value if only the Value is '0' by using For Loop Function..

Thanks and Regards,

Try this

Main:
LOAD *,
	 Date(MakeDate(Year, Month(Date#(Month, 'MMM'))), 'MMM-YYYY') as MonthYear;
LOAD * INLINE [

    2, Nov, 2018, 2000001
