Merging in Power Query

[Anonymous]

Merge always gives me a headache. 

Situation is:  

I have a table of opportunities with an Opportunity ID.     I have another table, called Quotes, that contains the Opportunity ID as well...but also has the column I need in my Opportunity table, which is, the Order number from our ERP table.   

I thought by merging the tables, using the Opportunity ID  with a Left Outer join would give me all my Opportunities in my current table, but then bring in just the Order number from the SF quote table.     I essentially want to match the Opportunity ID from both tables, so that for those Opportunities that have been coverted, the Order number will show up in the new column.  

But in doing so I went from 9600 rows in my Opportunity table, to 23000.    Is it possibly a granularity issue?

Hi @Anonymous,

How about use relationship mapping two tables instead of directly merge these tables in the query editor?

For this scenario, you can extract two table id field values and use them to create a bridge table with unique keys to link two tables.

have you checked the rowcounts on both tables?     Is it not possible that a customer has more than one quote but then i suppose the opportunity id would be different?  If not check for duplications.  What are you joining on?  best to share some of the data.
