Adding back combo/mod data to main item line

[sammytummy]

Hello all, 

I have a dataset on some food sales data and I would like to transfer all the combo and modification attributes back to the main item line. The tricky part is that some involve replacing new modified attributes with existing ones as well as some include adding extra patty to an existing patty value. I was thinking of using multi-row formula but I could not get anywhere with it. 

I have provided the sample data and the desired output. 

Appreciate any sort of help or ideas! 

Thanks all!

Hey @sammytummy ,

Here's one way you can go about answering that question. It's not the most dynamic way, but you can use it as a proof of concept and solve any issues that may arise when using the actual data.

Hope that helps,

Angelos

Thanks for the reply @AngelosPachis! I am making progress using your logic but I am having problems with adding the numbers after concatenating the fields. I was trying to use regular expressions but I am not too good at it so I am just wondering if anyone can help with that. 

My attempts: 

1. Remove the oz and turn the string into int. But I am not so sure how I would go from there to add the numbers.

2. Use regex_replace to get find the numbers only if there is a comma in the column. But I am not sure how to add the numbers if there is more than 2 (i.e. 3333=12) 

TLDR: How to make a string of 3oz,3oz into 6oz.
