Hi gpiero
Try this one with Table 1
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcivKTEms1FFwLE0vLS5RMNZRMDIwtFDSUVIwVFCK1YlWCk9NyUstBqsJTi0oSc1NSi1SMMVQFpJRWgRR5Z9ckg9SY4RFUWkqqhpjA1Q1sQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [CreatedDate = _t, IDAnomaly = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"CreatedDate", type date}, {"IDAnomaly", Int64.Type}}), #"Merged Queries" = Table.NestedJoin(#"Changed Type",{"IDAnomaly"},Table2,{"IDAnomaly"},"Table2",JoinKind.LeftOuter), #"Added Custom" = Table.AddColumn(#"Merged Queries", "Custom", each let mytime=[CreatedDate] in Table.SelectRows([Table2],each mytime>=[StartPeriod] and mytime<=[EndPeriod])), #"Expanded Custom" = Table.ExpandTableColumn(#"Added Custom", "Custom", {"TimeContr1", "TimeContr2"}, {"TimeContr1", "TimeContr2"}), #"Removed Columns" = Table.RemoveColumns(#"Expanded Custom",{"Table2"}) in #"Removed Columns"thank you very much, your help is like a tresure.
It works,
Thanks again:smileyhappy:

You can follow the steps from Query Editor
Bascially you merge the 2 tables using anomaly column
then
Use Table.SelectRows to select the relevant row from Table 2
