RVV50R10C user profile customizing vs. Variant

Hi,

we setup RVV50R10C arsenic a occupation with a Variant. 

In the tab User Role for our Variant we prime a User Profile and emblem the tract "List of blocked documents" arsenic 1 (List contains lone blocked orders) to debar duplicated transportation creation.

However successful the CUstomizing of the User Profile the field "List of blocked documents" is marked arsenic BLANK (Construct database without papers block).

Now during respective Job runs we sitll got duplicated deliveries.

Does the customizing of the User Profile overwrite the Variant erstwhile executed arsenic a Job successful Background?

SNote https://me.sap.com/notes/1454193/ only gave hint regarding customizing.

Thank you successful advance
