We want update a field "Worlog" with the concatenation of this field and the informations of the field "new info".
For example :
When service call is modified where New info (*) is anything Update data Worklog set to We click on Function We choose Concatenate and after, how to choose Worklog in "Value"? How to choose New info in "With"?
If we click on Attribute, choose a field, and click on OK, we have Worklog set to "the field in Attribute".
there are some postings on this. Have a look here to get going. Basically you will need to set a number of concatenations for thsi to work. I find knowing how many concatenations you need is the trick.
