Hi All, i have this script:

RIGHT('0' + CAST (SUM(CONVERT(decimal(8,4),cdv.value))%60 AS INT),2) AS '[HH:mm]'
,CONVERT(INT,SUM(CONVERT(decimal(8,4),cdv.value))) AS 'TotalMinutos'
FROM testprojects tproy (NOLOCK)
INNER JOIN testplans tplan (NOLOCK) ON tproy.id=tplan.testproject_id

give me this error:
GROUP BY, HAVING, or aggregate functions are not allowed in the recursive part of a recursive common table expression 'Estimated'.

The error you are getting is true: GROUP BY/HAVING,etc are not allowed in the recursive part of a CTE. It does not look like you are trying to do a recursive CTE but your UNION ALL statement is causing SQL to interpret your query that way....
You have two options:
1. You may be able (hard to tell without any DDL [hint]) to get away with using UNION instead (assuming you don't need duplicates) and that should solve your problem.
2. Insead of a CTE use a subquery... Something like:
SELECT id,parent_id,name = SPACE((nodes_level -1)*4) + name,nodes_level,jerarquia
FROM
(
SELECT nh.id,nh.parent_id,tproy.prefix,nh.name AS 'PLAN',Levelnodes=1,
Jerarquia = CAST('\'+CAST(nh.name AS VARCHAR(200)) AS VARCHAR(MAX))
,CONVERT(VARCHAR,CONVERT(INT,SUM(CONVERT(decimal(8,4),cdv.value))/60)) + ':' +
RIGHT('0' + CAST (SUM(CONVERT(decimal(8,4),cdv.value))%60 AS INT),2) AS '[HH:mm]'
,CONVERT(INT,SUM(CONVERT(decimal(8,4),cdv.value))) AS 'TotalMinutos'
FROM testprojects tproy (NOLOCK)
INNER JOIN testplans tplan (NOLOCK) ON tproy.id=tplan.testproject_id
INNER JOIN testplan_tcversions tcver (NOLOCK) ON tplan.id=tcver.testplan_id
INNER JOIN cfield_design_values cdv (NOLOCK) ON tcver.tcversion_id=cdv.node_id
INNER JOIN nodes_hierarchy nh (NOLOCK) ON tplan.id=nh.id
WHERE tproy.id=2
AND cdv.value NOT like '%[A-Z]%'
GROUP BY tproy.prefix,nh.name,nh.id,nh.parent_id
UNION ALL
SELECT nh.id,nh.parent_id,tproy.prefix,nh.name AS 'PLAN',Levelnodes=1,
Jerarquia = CAST('\'+CAST(nh.name AS VARCHAR(200)) AS VARCHAR(MAX))
,CONVERT(VARCHAR,CONVERT(INT,SUM(CONVERT(decimal(8,4),cdv.value))/60)) + ':' +
RIGHT('0' + CAST (SUM(CONVERT(decimal(8,4),cdv.value))%60 AS INT),2) AS '[HH:mm]'
,CONVERT(INT,SUM(CONVERT(decimal(8,4),cdv.value))) AS 'TotalMinutos'

Also,
I'd get rid of those NOLOCK table hints. NOLOCK (READ UNCOMMITTED) is for when you don't care if you always get the right answer. Here's a good article about that:
SQL Server NOLOCK Hint & other poor ideas.

Actually the OP is doing a recursive cte. The cte is named Estimate and the second half joins to it.
You will probably have to use your cte to return the raw data and then do your aggregates.
Also, get rid of those NOLOCK hints. Do you know all the nasty stuff that goes with those hints? Missing and/or duplicate data? Impossible to recreate bugs.

ok I get it on the NOLOCK. Thanks.@alan.B
your query give me this error:
Invalid object name 'Estimated'. 🙁
That is because he missed that you had a cte named estimated. The query he posted is trying to do a join to it but it doesn't exist.

I am having a hard time trying to figure out what you are trying to do here. Your original query has a recursive cte but you don't reference the original values in the recursive part. You seem to have multiple levels of aggregation here too which is very confusing.
Something like this might be getting closer. However in your original query you referenced nodes_level in the select but it isn't listed in the cte. I am not sure what that column is or where it comes from.

Thanks.
I modified the script a bit and doesn't generate errors:-), but isn't listing the desired result .. please see document attached (img_1/DataExample.txt). If you can see the nodes_level with hierarchy..
Please img_2 to see the result of your script
thanks for your help, any questions please let me know.
Thank you again!

That's because you added aggregates back into your recursive cte.
