Peek function doesnt work properly

Hi!

I have a table with Employees, Account , DataAccount,Bench

This is a part of my table:

I need to find the last row before the values in Bench appear like this:

This should work:

Data_raw:

  LOAD *, DATE(DATE#(Period, 'MMM-YY')) AS Date INLINE [

     Employee, Account, Period, DataAccount, Bench

     Mark Spencer, Telecom, Feb-15, 1.00, 0

     Mark Spencer, Telecom, Mar-15, 1.00, 0

     Mark Spencer, Telecom, Apr-15, 1.00, 0

     Mark Spencer, Telecom, May-15, 1.00, 0

     Mark Spencer, Telecom, Jun-15, 1.00, 0

     Mark Spencer, Telecom, Jul-15, 1.00, 1

     Mark Spencer, Telecom, Aug-15, 1.00, 1

     Mark Spencer, Telecom, Sep-15, 1.00, 1

     Mark Spencer, Telecom, Oct-15, 1.00, 1

     Mark Spencer, Telecom, Nov-15, 1.00, 1

     Mark Spencer, Telecom, Dec-15, 1.00, 1

  ];

Data:

  LOAD

  *,

  IF(Employee = PEEK(Employee) AND Bench <> PEEK(Bench), 1) AS Flag

  RESIDENT

  Data_raw

  ORDER BY

  Employee ASC,

  Date DESC;

DROP TABLE Data_raw;

this has been working for me

if(Employee = Previous(Employee) and Account = Previous(Account) and DataAccount = Previous(Account),

     if( Previous(Bench)= Bench, peek('Flag') 1),0) as Flag

peek ('Flag') expression isn't working

In this case you have to explore the next record to see if the bench has change, but this is no possible.  In this case i do the following:

T1:

Load.... " your table"

Then...

Join (T1)

Load Employee, Account, Max(Period) as Period, DataAccount, Bench, 1 as Flag

Resident T1

Where Bench = 0

Group By Employee, Account, DataAccount, Bench;

Check it out...

LOAD Employee,

     Account,

     Period,

     DataAccount,

     Bench

FROM

[Test.xlsx]

(ooxml, embedded labels, table is Sheet1);

temp:

load

  Employee,

     Account,

     Period,

     DataAccount,

     Bench,

     if(Employee = Previous(Employee) and Account = Previous(Account) and DataAccount = Previous(DataAccount),

     if(Previous(Bench)= Bench, peek('Flag'), 1),0) as Flag

resident temp

order by Employee,Period,Account ;

drop table temp;

if you only want it to show for when the change happen switch it to this

if(Employee = Previous(Employee) and Account = Previous(Account) and DataAccount = Previous(DataAccount),

     if(Previous(Bench)= Bench, null(), 1)) as Flag

I want to mark the row just before the change happens

I think you can use the last solution if you do this:

...

Order by Employee, Acouunt, Bench desc, Period desc;
