Mapping concatenated SKUs in a product string via Classification to Product Name


Level 2

I have a scenario where we have products grouped together in a single product string. You can imagine a watch store where the watch body and the watch strap have their dedicated SKUs.


In an ideal world, our engineers would've split the information in a format as such:


product = watch accessory;SKUBAND;1;60,watch body;SKUBODY;1;400

Unfortunately, what I have instead is something like this:

product = watch;SKUBAND+SKUBODY;1;460

I first considered building a .tab file to feed into the SAINT classification tool. I know this is a combinatorics exercise, where I can create a .tab file of all possible combinations.

However, if SKU is the 'index'/'key' of the .tab file for classification, then I cannot map multiple keys to the same product name.

For example, the following is not an acceptable data entry:



Any recommendations on how I can map concatenated SKUs to product names?

What about having two Product Classifications set up... one for Body and one for the Band.





So let's say your SKU is passed as 12345+67890 (where 12345 is the band "black leather" and 67890 is the body "silver face")


Now when you create your mappings, you can use Regex:


// or


Note: your SKU will likely be more than just digits (\d), but for example this... you will notice that I use Regex Groups for the first and second SKU with a literal "+" as the delimiter.... and now I am looking to match the first or last group.


For items matching "12345+[some SKU]" you can map into the Band Classification

For item matching "[some SKU]+67890" you can map into the Body Classification


So that:

12345+67890 will have classification "Band" with a value of "black leather" and a classification of "Body" with a value of "silver face"
and 12345+62672 will have classification "Band" still be "black leather" but will have a different Body Classification, maybe "gold face", etc

This is a great approach, though I may need a bit of clarification on how can I map the SKU to product name if I'm using Classification Rule builder which uses Regex.


Would this be the correct line of thinking:

  • Create a classification rule builder to split the SKU into watch band and watch face
  • Pass a SAINT file to map the SKUs collected in watch band to their respective product name
  • Pass a SAINT file to map the SKUs collected in watch face to their respective product name

Does this sound right?

Technically you aren't really splitting the SKUs, but you are creating groups so that you can match either the first or second SKU against your import file.


So starting with a simple example, a single SKU approach...


You have an import file with a list of SKUs... doing a 1 to 1 matching.

12345 = X

12346 = Y

12347 = Z



But you have 2 SKUs combined...

So you can use Regex and look at either Group A ($1) or Group B ($2)


When matching Group A, you will have the literal SKU you want to match in the first set of () then in the second you have a regex that will match any SKU. So for your Watch Bands, it doesn't matter what Body is paired, you are only matching against the first part and placing that into the Band Classification.


Then you have a second set of matching rules for Group B, where you use a regex that will match any SKU in the first set of () and then you use the literal SKU of the Watch Body to match no matter what band is paired... then you enter those values into the Body Classification.


So let's say bands are letter SKUs and bodies are number SKUs:


Combined SKU Band Classification Band Classification Regex Body Classification Body Classification Regex
X+1 Band X (X)\+(\w)+ Body 1 (\w)+\+(1)
X+2 Band X (X)\+(\w)+ Body 2 (\w)+\+(2)
X+3 Band X (X)\+(\w)+ Body 3 (\w)+\+(3)
Y+1 Band Y (Y)\+(\w)+ Body 1 (\w)+\+(1)
Y+2 Band Y (Y)\+(\w)+ Body 2 (\w)+\+(2)
Y+3 Band Y (Y)\+(\w)+ Body 3 (\w)+\+(3)


If you look, there are really only 5 unique regex for these combinations (two for either Band X or Y; and three for Body 1, 2 or 3)


Basically the Regex for both Bands and Bodies will be in one Classification Import, you will just have a unique regex for each potential band, and a unique regex for each potential face.
