Dynamically Merge Tables Based on Parameter

Hi,

 

 I'm currently taking a PDF order sheet and 'converting' it into a standard format "PDFQuery1" then I merge that into "LoadQuery" that is checking our ERP system for stock, jobs, delvieries etc.

This works fine, so well in fact we now want to expand this to other customers (great!) however each PDF is in a different format so I have created "PDFQuery2" that will convert Customer B pdf into our standard format no problem.

 

Now in my issue is in "LoadQuery" I want to use a paramater, customer code that end user popualtes, to determine which "PDFQuery" to merge in...

 

Original step

= Table.NestedJoin(PDFQuery1, {"CustItemRef"}, PM_Item, {"CustItemRef"}, "PM_Item", JoinKind.LeftOuter)

Attempt 1

 - Add Cust Code

let
Source = Excel.CurrentWorkbook(){[Name="CustCode"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"CustCode", type text}}),
CustCode = #"Changed Type"{0}[CustCode]
in
CustCode

 

then use this to repalce the fixed query name

 

= Table.NestedJoin(CustCode, {"CustItemRef"}, PM_Item, {"CustItemRef"}, "PM_Item", JoinKind.LeftOuter)

however this errors

Expression.Error: We cannot convert the value "10264" to type Table.
Details:
Value=10264
Type=[Type]

 

** PDFQuery1 is actually named 10264 at this point

 

Now I have a work around which is merge all the "PDFQueries" then filter rows based on CustCode however it doesn't seem like a great solution 😞

Had a look elsewhere and only finding solutions for dynmaic columns but always from a fixed query/table so any help appreciated!

 

Thanks,

The dynamic table name might help you, please kindly refer to

Thanks for the heads up. I haven't been able to get it working today but I'll keep going at it and try to work out where i'm gonig wrong and mark as resovled if/when i get there.

 

Funnily enough last night I went down the 'if' statement route as a slightly better workaround so good to see I wasn't the only person to try that 🙂
