Getting dates from different tables into main tables

[mohammadyousaf]

Hi, can someone please help me with a dax..

I have imported data from SQL and there are more than 80 tables.. the sample is like this

Table 1

Task ID	Task Name	Star Date	End Date
1	A
2	B
3	C

Table 2 - Task ID-1

Task ID	Date
1
1
1
1

Table 3 - Task ID-2

Task ID	Date
2
2
2
2

I have several such tables .. I want to calculate min & max date and insert them in table-1 in Start & End Date.

My relationship are one to many for these tables. 

Thank you.

Hi @mohammadyousaf ,

According to your description, refer to the following formula whether it can meet your needs.

M_min = 
CALCULATE (
    MIN ( Table_dimension[Date] ),
    FILTER ( ALL ( Table_1 ), Table_1[Catesgory] = MAX ( Table_1[Catesgory] ) )
)

M_max =
CALCULATE (
    MAX ( Table_dimension[Date] ),
    FILTER ( ALL ( Table_1 ), Table_1[Catesgory] = MAX ( Table_1[Catesgory] ) )
)

If the problem is still not resolved, please provide detailed error information and test data. Looking forward to your feedback.

Best Regards,
Henry

Thank you.. it worked only for one table for me since I don't have date table. Each Table has its own dates and I am unable to connect it to date table as my data model is very complex, let's say around 100 tables imported from SQL. 

Can you please assist me on creating variable and collecting dates or quantity from rest of the tables. 

Thanks.

@mohammadyousaf I think the first thing you should do is to append all of your Task ID tables together. Then you could create a single relationship and pretty much done.

I already have a table with Task ID which is table-1, I need to collect the max and mi date against each ID from the corresponding tables.
