calculate days count between 2 dates

[Wadda7AboUdai]

Hello Everyone 

I want to calculate days starts with item purchese date to item transfer date , items can be more than ones in the table it means can be purchesd more than ones and for all branches , I want to calculate the days  for each branch and sorted by dates if there are more than one purches order 

Here is the source table 

item	transaction number	type	date	decs	branch
A	01	3	01-01-2024	purchase order	A
A	01	22	10-01-2024	Transfer order	A
A	02	3	07-01-2024	purchase order	A
A	02	22	14-01-2024	transfer	A
B	03	3	01-01-2024	purchase	A
B	04	3	01-01-2024	purchase	B
B	03	22	13-01-2024	transfer	B

I want to Get the result like this 

item	transaction number	branch	Days Count
A	01	A	9
A	02	A	7
B	04	B	12

To calculate the number of days between the purchase date and the transfer date for each item in Pow...12. Here’s an example of how you might write this:

Days Count = 
CALCULATE(
    DATEDIFF(
        MINX(FILTER(Table1, Table1[type] = 3), Table1[date]), 
        MAXX(FILTER(Table1, Table1[type] = 22), Table1[date]), 
        DAY
    ),
    ALLEXCEPT(Table1, Table1[item], Table1[transaction number], Table1[branch])
)

In this formula, Table1 is the name of your table. This formula calculates the number of days between the minimum date (purchase date) and the maximum date (transfer date) for each combination of item, transaction number, and branch. The ALLEXCEPT function is used to remove any filters that might limit the rows being evaluated, exce...12.

Please replace Table1 with your actual table name. If you need further assistance or have more specific requirements, feel free to ask! 😊

Hi @AnalyticsWizard 

Thank you for your Replay , I want to inform you that the transaction number is different between purchase and transfer order 

the purchase order transaction number can be (scr-10023)

the transfer number can by (scr-2324)

and so on there is no related betwwen them

Hi @Wadda7AboUdai 

this can be a measure. Place [Item], [TransactionNumber] & [Branch] in a table visual along with the following measure:

Days Count =
VAR CrrentTransactions = 'inventtransn'
VAR PurchaseDate =
CALCULATE (
MIN ( ' inventtransn'[DATEPHYSICAL] ),
'inventtransn'[REFERENCECATEGORY] = 3
)
VAR TransferDate =
CALCULATE (
MAX ( ' inventtransn'[DATEPHYSICAL] ),
'inventtransn'[REFERENCECATEGORY] = 22
)
RETURN
IF (
NOT ISBLANK ( TransferDate ),
DATEDIFF ( PurchaseDate, TransferDate, DAY )
)

@tamerj1 
Thank you sp much for your help this worked fine with me when the item comes one time , when item comes more than one time I want to calculate days between REFERENCECATEGORY 3 and the next REFERENCECATEGORY 22 it means first find the first purchase date and go to next transdate not to last trans date , in the below picture it should calculate 3 time for the same item 

I want to show me the item 3 times each time how many day different 

[tamerj1]

@Wadda7AboUdai 
Yes that is because in expected result that you have presented, the transaction number is part of the filter context. If you place the transaction number in the result summary table it should work. However, the following should work in both senarios.

Days Count = 
SUMX ( 
    SUMMARIZE ( 
        'inventtransn',
        'inventtransn'[item],
        'inventtransn'[transaction number]
    ),
    VAR PurchaseDate =
        CALCULATE (
            MIN ( 'inventtransn'[DATEPHYSICAL] ),
            'inventtransn'[REFERENCECATEGORY] = 3
        )
    VAR TransferDate =
        CALCULATE (
            MAX ( 'inventtransn'[DATEPHYSICAL] ),
            'inventtransn'[REFERENCECATEGORY] = 22
        )
    RETURN
        IF (
            NOT ISBLANK ( TransferDate ),
            DATEDIFF ( PurchaseDate, TransferDate, DAY )
        )
)

Hi @tamerj1 

After applied this measure it shows balnk in result table 

[tamerj1]

@Wadda7AboUdai 

Can you please add the [VOUCHER] column to the detailed table visual and share a screenshot?

[Wadda7AboUdai]

showed Blank 

[tamerj1]

@Wadda7AboUdai 

I meant in the detailed table not the in tge summary table. 

[Wadda7AboUdai]

[tamerj1]

@Wadda7AboUdai 

In the sample data presented in your original post, there was a column called [Transaction Number] that identifies every purchase cycle of each item. In my dax I have used that column which you have replaced, for some reason, with [Voutcher] column. 
please calrify this point. 

[Wadda7AboUdai]

Hi @tamerj1 

I named that transaction number just to make it more simple to explain the table content 
Voutcher is the same thing has  uniqe number for each transaction ,I apologize if I did not explain this more simply

[tamerj1]

@Wadda7AboUdai 

Except it is not the same thing. Voucher defines each single transaction. What is required is a column that groups the transactions that belong to each cycle. If such column does not exist then it has to be created. If not coming from the source then I would say that won't be an easy job. 

[Wadda7AboUdai]

@tamerj1  Yes, that is correct. Could the method be to search for the first purchase transaction and then calculate the date Different to transfer order  closest to the purchase date?

[tamerj1]

@Wadda7AboUdai 

That won't work. In your original post example (item B, transaction number 3) has to be skipped as it hasn't been transferred to branch. The closest transfer date to this transaction is the one that belong to B-4. To identify that this transaction has not been transferred we need to do more work. 

This is very similar to attendance data where you have multiple punch in and punch out in a given date. It's not that it is not possible but it is a bit complicated and probably requires creating a new calculated table.

Best option is to have this identified from the source or at least calculated easier with SQL.

Hi @Wadda7AboUdai ,

@lbendlin , thanks for your attention to this situation. I tried to modify the data myself and implement the result according to the user's request. Please check if it can be improved. Here is my solution:

1. create a calculated column to get the number of days between intervals.

Days Count =
VAR PurchaseDate = CALCULATE(MIN('Table'[date]), 'Table'[decs] = "purchase", ALLEXCEPT('Table', 'Table'[item], 'Table'[branch],'Table'[transaction number]))
VAR TransferDate = CALCULATE(MAX('Table'[date]), 'Table'[decs] = "transfer", ALLEXCEPT('Table', 'Table'[item], 'Table'[branch],'Table'[transaction number]))
RETURN
DATEDIFF(PurchaseDate, TransferDate, DAY)

2. Create a calculation table to get the desired result.

Summary Table =
var _table=
SUMMARIZE(
    'Table',
    'Table'[item],
    'Table'[transaction number],
    'Table'[branch],
    'Table'[Days Count]
)
return
FILTER(
    _table,[Days Count]<>BLANK())

If your Current Period does not refer to this, please clarify in a follow-up reply.

the categoryreferance  3= purchse , 22 = transfer 

[lbendlin]

[Wadda7AboUdai]

still not transferd to branch
