MIM Advanced attribute Flow Precedence

Hello everyone,

i struggling a little with a MIM Sync Engine i'm currently implementing

it syncs from AD to an SQL DB while Generating Emails and checking for duplicates .

so what i need to do is generate a unique email when synchronizing to SQL, then replace the value in AD with this new value 

SQL then becomes PRecedent over AD for Mail attribute

i have the following flow:

AD Mail to Metaverse Mail to SQL Mail

with an EAF from metaverse to SQL where i check for duplicates and generate the mail, 

my issue is that for some reason, when i sync, my flow shows as skipped not precedent... its unique one way flow, i don't understand what precedence is doing here ?

any ideas ?

i've added some snapshots by i can add more if needed

Thanks!
