Compare/Count a field in a datapil to other records in the same datapil without looping?

[johnw]

I have an Epicor BAQ report I use in Workato that gives me a list of all SKUs in an order and their shipping information

99.9% of the time all the SKUs in an order will be on the same pricebook but on rare occasions 2 SKUs might on pricebook X and 1 SKU on pricebook Y so each record in the BAQ report will have a pricebook field 

is there a way in workato to count the number of different prciebooks or do i have to loop through each record to count them?

thanks

I don't know how your data is structured, but you can use a combination of pluck and uniq to accomplish what you need.

Here's how they work:

list = [
    {"book": "a"},
    {"book": "a"},
    {"book": "b"}
]

books = list.pluck("book") 
## outputs ["a","a","b"]

uniqbooks = list.pluck("book").uniq 
## outputs ["a","b"]

uniqbooks.size 
## outputs 2, the number of items in the array

You can do it directly from the output of the Epicor action.

Also, just a heads up that will hopefully save you some time...

When you use .pluck you need to refer to a data pill by its "API key", which is the schema key and NOT it's readable label. This usually trips people up when using methods on connector data pills with really long labels, or when the label and the key are completely different.

To see the API key, just hover over the data pill. If you were to pluck the pill below, you would use .pluck("field_1") and not .pluck("blah blah blah...")

I'm mentioning this because you might have to pluck "Price list 2 of price book ID 18 char c" and I would be very surprised if that label was also the API key.

how would pluck be used to see if there were any blank/empty fields?

was thinking something like this:

["value"].pluck('PriceLstParts_SfPriceBookEntryId18Char_c').count("") > 0

When data is missing, it should be missing in a few different ways:

• The key is missing
• The key is present and the value is ""
• The key is present and value is null

If the key is always present and a blank value is "", then this will work!

got twisted around and needed to add a null option so this fixed my issue:

["value"].pluck('PriceLstParts_SfPriceBookEntryId18Char_c').count(null) > 0
