Hi Dan,
 I can’t find the solution with row filter.
 I want for each V……. number to remove the rows 
 - Levertermijnen klant
 - Levertermijnen leveranciers
 - magazijn
 - programmeur
 - service
 - projectleider - technieker
 - verkoop
 - werkvoorbereider
 This way all the empty rows are hidden and the events follow each other in a row
