Dear gurus,

We've been trying here to fight an issue where we can't get to a solution.

We have a table like:

A abrf
B bdkw
C jfgd
A jfdk
E jkfg
B roer

(where the single char is column A and the 4 letters are column B)

The goal was to have in column C the merger of the values in column B for which the value in column A is the same, like:

abrf-jfdk
bdkw-roer
jfgd
abrf-jfdk
jkfg
bdkw-roer

Can someone give us a hand?

Highly appreciated.
