Collections ValueExpression and Parent Data

[ChrisFrancis93]

I have built a task report.  I am accessing the Predecessor collection as follows:

displayname=Predecessor Planned Lag
listdelimiter=<p>
listmethod=nested(predecessors).lists
type=iterate
valuefield=predecessor:actualCompletionDate
valueformat=HTML

but what I would really love to do is get the WEEKDAYDIFF of the predecessor Actual completion Date and the current task actualStartDate

displayname=Predecessor Planned Lag
listdelimiter=<p>
listmethod=nested(predecessors).lists
type=iterate
valueexpression=WEEKDAYDIFF({predecessor}.{actualCompletionDate}, {CURRENT TASK ACTUAL START DATE})
valueformat=HTML

Is it possible to reference a field on the current object within a collection field like this, and if so, how?

that isn't possible at this time.

Thanks.  Boo but thanks for the quick reply.

haha I hear ya. I think you should think about other dates that might serve the same purpose. Have you looked into using the current task's handoff date? I feel like the handoff date is the date it was handed off from the predecessors, and that would keep you on task without looking upstream into collections.

Well that is helpful.  Didn't even know that was a standard field.  Thank you
