Link between 3 tables for a new column

Hi Stephane1974 ,

Based on your description, I have created a simple sample:

Please try:

tblResults = 
var _a = FILTER('table2',[tbl2Dim3_StartInterval]<=[tbl1Dim3]&&[tbl1Dim3]<=[tbl2Dim3_EndInterval])
var _b = FILTER('table3',CONCATENATE([tbl3Dim2],[tbl3Dim3])=CONCATENATE([tbl1Dim2],[tbl1Dim3]))
return SWITCH(TRUE(),
COUNTROWS(_a)>=1,MAXX(_a,[tbl2Results]),
COUNTROWS(_b)>=1,MAXX(_b,[tbl3Results]))

Final output:

Best Regards,

Jianbo Li
