Unless you're using a super old version of SQL Server, this should work fine:

SELECT [Policy]

, BatchMonth

, Amount

, LAG(Amount,1) OVER (PARTITION BY [Policy] ORDER BY BatchMonth) AS PrevMonthAmount

FROM #dummy

ORDER BY [Policy],...

Your tables are pretty, but that's not a helpful way to post sample data. Useful is stuff we can copy & paste into SSMS and run it. Please read this...

Thanks!

Any suggestions where to start?

This is close... hopefully someone can figure out the one part I can't.

I wonder if I can upload .rar files... wish me luck.

Don't you determine entities and relationships first, and then determine groupings of those and put those into schemas?

Your questions are REALLY vague. Maybe you should clarify them.

Jeff,

Gotta get some sleep... Just got home, so I'll do it in the morning sometime. It's a really simple tree with 3 levels, but I think it's enough to get...

Just to explain it to myself or visualize what's going on, I drew a tree of parts with assemblies etc. I started with something I could get my head around...

Something like this? (Use a Calendar table).

use tempdb;
GO
-- count the dates between two days excluding weekends
CREATE TABLE #Calendar (TheDate DATE PRIMARY KEY CLUSTERED);
GO
DECLARE @TheDate  DATE = '01-Jan-2019'
WHILE...

Got some dummy data? Create table script... you know the drill.

That’s what I was thinking. Get max of level and return all parts having that same level.

Makes sense! Thanks!

This worked... ugly, but it worked:

DECLARE @string VARCHAR(200) = 'All I want (for Christmas) is better (TSQL) coding skills (this year).'
--remove everything between parens
--remove the parens
DECLARE @StartPos...
