Filling Empty Cells

Thu, 02 Jul 2015 13:01:49 GMT

Hello experts,

I am trying to do the following. I have a table that has a column of vendor IDs and another column with line numbers. The problem is that is there are multiple lines, which is almost always the case, the vendor number will only appear in the last line. I also have a copy of this vendor number column as a new column. I would like to pupulate the cells in the new row with the vendor number of the last line in the invoice. For example:

I have:

Invoice Line Number Vendor1 NewVendor

1 1

1 2

1 3 101

2 1

2 2

2 3

2 4

2 5 102

What I would lke is:

Invoice Line Number Vendor1 NewVendor

1 1 101

1 2 101

1 3 101 101

2 1 102

2 2 102

2 3 102

2 4 102

2 5 102 102

Any ideas how I could perhaps sort descending and peek back??

Thanks,

Dave

create a separate table with only invoice and max(vendor1) and then left join it to the original table.

you could do the same but instead of left joining you could use ApplyMap

Thanks! If this works, I think you have made my work a whole lot easier in a few other ways! I will let you know!

Try this script:

Table:

LOAD Invoice,

[Line Number],

If(Len(Trim(Vendor1)) = 0, 0, Vendor1) as Vendor1;

LOAD * Inline [

Invoice, Line Number, Vendor1

1, 1,

1, 2,

1, 3, 101

2, 1,

2, 2,

2, 3,

2, 4,

2, 5, 102

];

NewTable:

LOAD *,

If(Invoice = Peek('Invoice'), Alt(Peek('NewVendor'), Vendor1), Vendor1) as NewVendor

Resident Table

Order By Invoice, Vendor1 desc;

DROP Table Table;

Output:

Try this script

//Your Data (Do not load New Vendor)
Tab:
LOAD * Inline [
Invoice, Line Number, Vendor1
1, 1,
1, 2,
1, 3, 101
2, 1,
2, 2,
2, 3,
2, 4,
2, 5, 102
];

//Retrieve the last invoice line
Left Join
LOAD Invoice, Max([Line Number]) as maxi Resident Tab Group By Invoice;

Left Join
LOAD Invoice, Max(Vendor1) as NV Resident Tab Where [Line Number] = maxi Group By Invoice;

Alessandro,

I tried your version, which seems to be what Ioannis was saying, replacing "Tab" with my datasource but get a message upon reload that the variable "maxi" could not be found....wouldn't the LOAD .. AS maxi... take care of that (the error is in the 2nd join=. Thanks for any ideas.

Hi,

Try like this

Data:
LOAD * Inline [
Invoice, Line Number, Vendor1
1, 1,
1, 2,
1, 3, 101
2, 1,
2, 2,
2, 3,
2, 4,
2, 5, 102
];

LEFT JOIN (Data)

LOAD

DISTINCT Invoice, Vendor1 AS NewVendor

RESIDENT Data;

Hope this helps you.

Regards,

Jagan.

I see were you are going with this but I kind of simplified the Invoice Number part. It is in fact, not unique by itself and Vendor is not distinct at all. Invoice Number & BusinessUnit & Year is distinct and is automagically joined by QlikView....I am new to this, coming from an SQL background where I would join everything myself. So my first thought is this will not work but I could give it a try if I can't get the other problem worked out in an easy way. Thanks! Dave

Hi,

In Qlikview the join is automatic based on the common field names, you cannot control that. You have to rename the fields accordingly as per the join requirement. If you share the exact sample data and your expected output then it would be easier to provide the solution.

Re: Filling Empty Cells

OK...what I have done so far is to create a join between the invoice header and the invoice lines (as they are stored in two different tables) and added a MAX(LineNumber) AS TopLine to that data set.....so now I have a new table that is only the 3 criteria to make it JOIN (combined are unique: InvoiceNumber, BusinessArea and Year) and added a "MAX(LineNumber) AS TopLine" in usinf SQL SELECT and called it MainData in QlikView.

Now, in QlikView preferably, but if I have to do it in SQL that is OK too. I want to take the LineItem table, JOIN with the MainData table I created above, basicially joining WHERE InvoiceNumber (LineItem) = InvoiceNumber (MainData) AND BusinessArea (LineItem) = BusinessArea (MainData) AND YEAR (LineItem) = YEAR (MainData) and filling each of these lines with MAX(LineNumber) aka TopLine from above.

Does that make it clearer or worse. I was asked to do as much in QlikView as possible but since I draw from an SQL database for most data, I need quite a bit of SQL.

Thanks again,

Dave

Hi sunindia,

If(Invoice = Peek('Invoice'), Alt(Peek('NewVendor'), Vendor1), Vendor1) as NewVendor

What Alt function will do in the above function?

Thanks in advance.

Hi Jagan,

I tried with your script. It is working fine. When I use table box, Null is getting for NewVendor.

Kindly advise.

Ioannis,

In keeping with your join idea, I have created a table with the three variables I need to make the Invoice unique (in order for it to be unique, I need to have the invoice number, business unit and year match each other) and another field with just the number of the highest line number (the one that contains the vendor). Given that one table has the unique combination to create a unique key and the highest line number and the second table also has the unique combination of keys, the line number and vendor ID, how would I construct such a join in Qlickview, where it would pull the vendor number down to all rows? Thanks in advance, Dave

Hi davidjgilligan,

Can you select Correct Answer to close the thread.Thank you.

Re: Filling Empty Cells

Mon, 06 Jul 2015 08:13:49 GMT

Yes, I hope to soon. I may have over simplified a bit bu just stating "Invoice" when 3 fields (one is the invoice) need to match before it is a unique key, so anything relying JUST on invoice (and not Business Area and Year) will not work as the invoice number gets reused yearly and by business area (I don't know why this is, but it is and I must accept this). Hopefully, I can modify one of the above and post what I got and mark an answer. Thanks, Dave

Hi davidjgilligan,

What is your issue? Can you post with sample data?

If your issue resolved, please close the thread. Thanks.

Re: Filling Empty Cells

Mon, 06 Jul 2015 08:36:21 GMT

Here is revised sample data:

Invoice Year BusinessArea Line Number Vendor1 NewVendor

1 2015 1 1

1 2015 1 2

1 2015 1 3 101

2 2015 1 1

2 2015 1 2

2 2015 1 3

2 2015 1 4

2 2015 1 5 102

3 2015 1 1

3 2015 1 2 101

1 2014 1 1

1 2014 1 2 102

1 2015 2 1

1 2015 2 2

1 2015 2 3 104

What I would lke is:

Invoice Year BusinessArea Line Number Vendor1 NewVendor

1 2015 1 1 101

1 2015 1 2 101

1 2015 1 3 101 101

2 2015 1 1 102

2 2015 1 2 102

2 2015 1 3 102

2 2015 1 4 102

2 2015 1 5 102 102

3 2015 1 1 101

3 2015 1 2 101 101

1 2014 1 1 102

1 2014 1 2 102 102

1 2015 2 1 104

1 2015 2 2 104

1 2015 2 3 104 104

WHERE the combination of Invoice, Year & Business Area is unique, not just invoice number. My bad in over-simplifying the specs. So I may have say 12 invoice #1s, 1 for each of 4 different business areas and 4 each business area over the past 4 years.

Thanks,

Dave

OK Wizard, I am going as fast as I can....the field names are not vendor and the script will not work as indicated because it is not an inline load. I need more than 1 minute to test this without 2 emails every post 30 seconds after posted.

That being said, 1000 thanks to Jagan....after some modifications it appears to work perfectly! Thanks again. Dave
