ddl with indexes

create table ExtractReports.dbo.TechnologyPlPartsFeaturValuesOrg
       ID int identity(1,1),
       PartId int,
       FeatureID int,
       FeatureName varchar(200),
       FeatureValue varchar(200)
       ALTER TABLE ExtractReports.dbo.TechnologyPlPartsFeaturValuesOrg
 ADD CONSTRAINT PK_TechnologyPlPartsFeaturValuesOrg PRIMARY KEY (ID);
 create index partidoriginalParts_ix on ExtractReports.dbo.TechnologyPlPartsFeaturValuesOrg(partid)
 create index FlagRecomendationorg_ix on ExtractReports.dbo.TechnologyPlPartsFeaturValuesOrg(featureid,FeatureValue)include(partid)
 create table extractreports.dbo.partsrecomendationActive
 RecomendationId int identity(1,1),
 RecomendationPartId int,
 OrignalPartId int
 create clustered index recomendations_ix on extractreports.dbo.partsrecomendationActive(RecomendationId)
 create nonclustered index recomendationsparts_ix on extractreports.dbo.partsrecomendationActive(RecomendationPartId)
 create nonclustered index recomendationsoriginal_ix on extractreports.dbo.partsrecomendationActive(OrignalPartId)
 CREATE TABLE [Technology].[Receipe](
     [ReceipeID] [int] IDENTITY(1,1) NOT NULL,
     [PLID] [int] NULL,
     [FeatureID] [int] NULL,
     [OperatorID] [int] NULL,
     [FeatureTypeID] [int] NULL,
     [ReceipeID] ASC

What I have tried:

statment that make issue

select a.RecomendationId,cast(STRING_AGG(cast(f1.FeatureValue as varchar(300)) ,'|')  WITHIN GROUP(ORDER BY f1.FeatureId ASC)as varchar(300))  AS DiffFeatures into ExtractReports.dbo.TechnologyOriginalFeaturesEqual from extractreports.dbo.partsrecomendationActive a with(nolock)
 inner join ExtractReports.dbo.TechnologyPlPartsFeaturValuesOrg f1 with(nolock) on f1.partid=a.OrignalPartId
 inner join [Technology].Receipe Ft WITH(NOLOCK) on ft.featureid=f1.featureid and ft.operatorid=1
 group by a.RecomendationId

The "query optimizer" is not a supreme being. You start with a simple query and build on it incrementally. That's how you determine performance issues before constructing a query that the "optimizer" can't deal with. You also make no mention of "record counts"; as if they are somehow immaterial to the discussion (they are not).
