Mapping or left Join

[bharatkishore]

Hi All,

I have two tables. In table A  i have Equipment and Posting Date.

In table B i have  [Sales Document],
Item ,
Equipment,
Start_DT_New,
End_DT_New,
MaterialEntered

Now for [Sales Document],Item ,  and MaterialEntered the condition is i need to get only records based on the below condition i.e.

if both the table  equipments matches and Posting Date>=Start_DT_New and Posting <=End_DT_New.

Can you please tell me how to achieve this and let me know if you need anything more.

Thanks,

Bharat

Do a mapping load and put a where condition on the resulting table may be.

I have tried that but the prob is for Ex:
i have in Table 1 i have 1 equipment number has record 1A
in Table 2 i have the same equipment number with two records 1A and 2A the output i will be getting is 1A and 2A even the duplicate reocrds.
But i need only matching records i.e. 1A no duplicate records..

Are you saying Equipment is not the most granular data and something else is? 

You need to filter the date condition right? If you need the data that is present in table 1 you can definitely do a left join , apply map will give you the flexibility to enter default value for the non matching rows. At the end you need to see what is feasible for the data set you are using.

I need to filter based on two conditions
1) when both the equipment matches in both the tables
2) when posting date is >=Startdate and posting date is <=Enddate. Hope i am clear..

Do a inner join and put a where condition on the resulting table . I think it will work for your case.

So mapping is a wrong choice? correct..

[pradosh_thakur]

if the column you are using for mapping is not the least granular then yes it's not a right choice. Again your case seems like it warrants an inner join.

OK Thanks. let me try and get back up to you..
I have tried mapping but i am getting duplicate records as well..

It sounds to me that you could benefit from using intervalmatch() with extended syntax. Take a look at the Qlik help section. https://help.qlik.com/en-US/qlikview/November2018/Subsystems/Client/Content/QV_QlikView/IntervalMatc...
