Use of Multiline Attribut

[John A Haworth]

Hi all
 
Please could someone advise on the following: I want to set a condition in
a workflow based on the value of a Partner Function from a sales document,
being a specific value. As there a number of possible Partner Functions
assigned to a single Sales Document, I imagine I need to define a Multiline
Atrribute at my sub-object and then have this hold all the values of the
Partber Functions. Then in my workflow have a mechanism for looking at each
line of the new attribute to search for my particular condition.
 
If I am on the right track, could someone advise me of how this can be
achieved.
 
Thanks in advance
 
John
