Hello everyone ! 

I am trying to add some roles to several BP with the help of LSMW 

I recorded the BP transaction (search of the BP, clicked on the bp number, then all of the relevant fields)

However, when running my batch input, lsmw process first looks for the Bp, then it comes back to this screen (image attached) which is throwing me an error... How can i proceed ?  

I know it is best practice to use MASS, but i'd like to have another possibility then that
