There is a slicer with the name of Equipment (Table B) 

When a Equipment selected, here for example:  Equipment:  GSC0B in table A, the code is 107501, then I use this code to search in column Parent, the result is below but it takes like forever to load this table: 

Nom_Equipement	Parent	Code_Barre	Size	brand
GSCNZ	107501	107502	24	HP
GSCSF	107501	107505	25	DELL
GSCZG	107501	107507	16	HP
GSC7T	107501	107516	19	DELL

I use the following measure : 

Flag = 
var _a = ALLSELECTED('Table B'[Equipment])
var _b = SELECTCOLUMNS(FILTER(ALL('Table A'),[Equipment] in _a),"Code",[Code])
return IF(SELECTEDVALUE('Table A'[Parent]) in _b,1)

Final output:

Thank you in advance for any suggestion to reduce the loading time.

Hi @vnqt 

You may try this measure. I hope it will perform faster. 

Flag = 
var _a = VALUES('Table B'[Equipment])
var _b = CALCULATETABLE(VALUES('Table A'[Code]),ALL('Table A'),'Table A'[Equipment] IN _a)
return
IF(SELECTEDVALUE('Table A'[Parent]) IN _b, 1, 0)

Thank you for your reply. Could you please share pbix cause I can't reproduce the same effect with your measure. 

Here is the screenshot with 2 measure : Flag 1 and Flag 2 ( your suggested measure)

There is no result with second flag measure: 

Here is the Relation of tables 

Thank you for your help.
