Try to load your table like this way

Source:

LOAD Date(Date,'D/M/YYYY') as Date,Outbal;

LOAD * Inline

[

Date, Outbal

1/1/2014, 100

2/1/2014, 500

3/1/2014, 200

4/1/2014, 400

5/1/2014, 150

6/1/2014, 450

7/1/2014, 300

];

NoConcatenate

NewTable:

LOAD

Date,

Outbal,

if(RowNo() = 1,Peek('Outbal',-1,'Source') ,Previous(Outbal)) as Inbal

Resident Source;

DROP Table Source;

Hi Anand,

Thanks for your answer but in source we have date values not in a order so we need perform order by with date.plz find the source.

[its_anandrjs]

Then try with this and creating order by for Date

tmpSource:

LOAD * Inline

[

Date, Outbal

1/1/2014, 100

2/1/2014, 500

3/1/2014, 200

4/1/2014, 400

5/1/2014, 150

6/1/2014, 450

7/1/2014, 300

];

NoConcatenate

NewSource:

LOAD Date(Date,'D/M/YYYY') as Date,Outbal Resident tmpSource Order By Date;

DROP Table tmpSource;

NewTable:

LOAD

Date,

Outbal,

if(RowNo() = 1,Peek('Outbal',-1,'Source') ,Previous(Outbal)) as Inbal

Resident NewSource;

DROP Table NewSource;
