Pivot or...?

Hi everyone, We have a system here that for every employee, that have to check in and check out with their own card. Of course not everybody do it by the book but that's why "we" are here, to see wh...

    okay, i think i've fixed that bug. Try this: 

    let
    Source = your_table,
    f = (tbl as table) as table => 
        [rows = Table.ToRecords(tbl),
        acc = 
            List.Accumulate(
                rows,
                {},
                (s, c) => 
                    if c[CLOCK_TYPE] = 51 then s & {c & [CHECKIN = c[DATETIMECHECK]] & [CHECKOUT = null]} 
                    else if List.IsEmpty(s) 
                        then s & {c & [CHECKIN = null] & [CHECKOUT = c[DATETIMECHECK]]}
                        else if List.Last(s)[CHECKOUT] = null 
                            then List.RemoveLastN(s, 1) & {Record.TransformFields(List.Last(s), {"CHECKOUT", each c[DATETIMECHECK]})}
                            else s & { c & [CHECKIN = null] & [CHECKOUT = c[DATETIMECHECK]]}     
            ),
        out = Table.FromRecords(acc)][out],
    g = Table.Group(Source, {"SHIFT_NUMBER", "EMPLOYEE_CODE"}, {"all", each f(Table.Sort(_, "ABS_NUMBER"))}),
    expand = Table.ExpandTableColumn(g, "all", {"CLOCK_DATE", "CHECKIN", "CHECKOUT"})
in

Thank you so much for your help AlienSx 
I think your solution maybe the one I need. Let me tell you what I got with both your solutions.
1st query : everything seems fine BUT this value (red) came from nowhere. The raw data doesn't have this.

The second query :

I think what you need to know is that every employee, choose to check in or check out (51 or 52) but also for each shift number he's in. That said, we have to see, for each shift number the check in and check out. You cannot mix shifts, but I think you knew this already. Can you change the 1st query accordingly?
Thanks a lot in advance

Hey, pedroccamaraDBI you could do that yourself - just add SHIFT_NUMBER as one of grouping parameters. Try this:

let
    Source = your_table,
    f = (tbl as table) as table => 
        [rows = Table.ToRecords(Source),
        acc = 
            List.Accumulate(
                rows,
                {},
                (s, c) => 
                    if c[CLOCK_TYPE] = 51 then s & {c & [CHECKIN = c[DATETIMECHECK]] & [CHECKOUT = null]} 
                    else if List.IsEmpty(s) 
                        then s & {c & [CHECKIN = null] & [CHECKOUT = c[DATETIMECHECK]]}
                        else if List.Last(s)[CHECKOUT] = null 
                            then List.RemoveLastN(s, 1) & {Record.TransformFields(List.Last(s), {"CHECKOUT", each c[DATETIMECHECK]})}
                            else s & { c & [CHECKIN = null] & [CHECKOUT = c[DATETIMECHECK]]}     
            ),
        out = Table.FromRecords(acc)][out],
    g = Table.Group(Source, {"SHIFT_NUMBER", "EMPLOYEE_CODE"}, {"all", each f(Table.Sort(_, "ABS_NUMBER"))}),
    expand = Table.ExpandTableColumn(g, "all", {"CLOCK_DATE", "CHECKIN", "CHECKOUT"})
in
    expand

    Hello AlienSx 
    I did add it to the group parameters but it stayed the same. That's why I thought something was wrong. I don't have enough knowledge to do this, you know.
    This new query seems to be the same as your 2nd above, only doubled the records

    We're supposed to have only 3 records, and the first one, with only the checkout date/time. Exactly how you see it above. In raw data, you have 5 records but after pivot or grouping, you should have only 3

        I believe you're on the right path AlienSx . Just one record missing

        your result is this one

        Don't give up please...
