I have been reading about the use of Apoc maps for about a week, but none of the stuff I have watched or read actually use it in the query.
This page https://neo4j.com/docs/labs/apoc/3.5/data-structures/map-functions/
gives examples of it with the return clause, but doesn't show me how to add it to a node as a property.
What I want to do is that the following.
I have an invoice that has sub invoices attached to it, so what I need to do is add the sub invoices as a a map in one of the properties.
The invoice is a reminder invoice so I want to add the two invoices to the node in a map in a variable, but the original invoices that are in the map I want to add as external nodes, The reason being to keep track of the originals in comparison to what they send on the reminder invoices. Will be used for comparisons down the line.
The information in the map will be key value pairs. I just don't understand as yet how to add the map to a property on a node. And also how to edit it later. I did read that Neo4J doesn't do edits on maps, so that is why I went and looked at APOC.
So here is a little example of what the data from the invoice looks like
InvoiceRefNR:1, Date:"09-02-2006", PricipalCost:33
InvoiceRefNR:2, Date:"04-01-2006", PricipalCost:456
How do I add this information to the node as a property with the name InvoiceRefNR
So the main node is:
Property: SubInv: (this will / needs to be a map of all the sub invoices)
I need to be able to access each sub invoice as it's own map. So I am alreay wondering if this will be a list of maps inside the SubInv property.
Bear in mind I am new to this, so the more detailed your explanation the better.
Thank you in advance.
