Is there a way to have rows as "Child" relationship under a "Parent" row?
I am sorry I did not respond until now - I actually just saw this! And actually, I am now just starting to move some processes onto Airtable. I still have a major issue as to how to achieve the original thing I asked about. Your explanation makes sense but I have a slightly complicated issue related to Accounts Receivable. I have attached two screenshots of how I am currently doing this outside of Airtable. The first of the screenshots shows the entire worksheet with the jobs all having a + sign next to the name. This is because when you click the + sign rows drop down beneath the “parent row”. These rows below represent the different phases of the one job. I also invoice based on phases, so we track when we do any activity (calls or emails to ask for payment) on the client level (Meaning we don’t call or chase “per phase” for our money, we do it overall on the client level). The issue I am having is want to look at the job as a whole (Meaning all phases) and we have to track the “estimate”, “payments to date”, and “balance due” per invoice. We also track when we submit each particular invoice. So the hierarchy of the sheet is really the best way to look at the overall goal. Doing it horizontal like the attachment shows allows for the minimum number of columns to achieve the overall result. Ultimately, I don’t know how to do something like this with Airtable, as they don’t seem to have the indent properties of the a typical spreadsheet. Any advice would be greatly appreciated (hopefully I am not asking too much!!). thanks in advance if you can offer any help.
