DATE AND TIME MATCHING WITH ERROR

[visittokiran]

I have following two tables with date & time table 

I want to fetch data in table A as shown below

	TABLE B
CODE	DATE & TIME	INCIDENT ID	ENTRY TYPE
H12345	01/10/2021 08:00	75769338	A
H76793	02/10/2021 08:00	79879893	B
H87974	03/10/2021 08:00	987979721	C
H89448	04/10/2021 08:00	3628643	E

TABLE A
CODE	DATE & TIME
H12345	01/10/2021 08:15
H76793	02/10/2021 08:30
H87974	03/10/2021 08:20
H89448	04/10/2021 08:05

Final result required 

TABLE A (FINAL)			DATA MATCHING WITH ERROR OF 30 MINS
CODE	DATE & TIME	incident	ENTRY TYPE
H12345	01/10/2021 08:15	75769338	A
H76793	02/10/2021 08:30	79879893	B
H87974	03/10/2021 08:20	987979721	C
H89448	04/10/2021 08:05	3628643	E

@BA_Pete  in both data tables there are multiple entried for same code ...

Hi @visittokiran ,

I'm not sure I fully understand your requirements here.

It looks like [CODE] is a unique field in both tables, so why not just merge tableA with tableB on tableA[CODE] = tableB[CODE]?

Sorry for late reply @BA_Pete , you are right but sorry i did not mentioned that in that data there are multiple entried in a days for same code. In that case how to match data ? 

[BA_Pete]

@visittokiran ,

OK, no worries.

Can you provide a more representative example of your data please?

If you can create an example of tableA and tableB in Power Query (Enter Data) then just post the M code for each that would be ideal.

@BA_Pete  I will try to explain in detail.

There are two data tables table A & Table B

I want to fetch data from table B to table A  or Creating dashboard will also be fine.

While fetching data from Table B following logic need to be implemented.

First for every row in Table A it first Code no will be checked.

IF code No Matched then Date will be mate if Date Matched then 

Time will be matched But time is not exact match in both table.

There is some time gap in time mentioned in table A.

So I want to match time with +-30 min span.

If time also matches then data from INCIDENT & ENTRY TYPE SHALL BE FETCHED IN TABLE A FOR THAT SPECIFIC ROW IN TABLE A.

@visittokiran  you can create a measure like this and utilize this a visual level filter

_filter = 
VAR _a =CALCULATE(MAX('table A'[DATE & TIME]))
VAR _b =CALCULATE(MAX('table B'[DATE & TIME]))
VAR _c = ABS(DATEDIFF(_a,_b,MINUTE))
RETURN switch(true(),_c=30||_c=0,1)
