We face a situation where an AD extensionAttribute is to be made up of 11 (ELEVEN!) separate source fields separated by hyphens.
I have tried my inbound to MV attribute flow to be both CustomFunction
(F1+"-"+F2+"-"+F3+"-"+F4.....+F11) -> extensionAttribute1
and 3 screens of concatenate source + string "-"
F1+"-"+F2+"-"... F11 -> extensionAttribute1
I have noticed once we get past 6 or 7 concatenated fields the destination receives null or is empty
Just how many concatenations is allowed in a Sync Rule?
Is the classic flow rule extension subject to any limitations on the number of source attributes that can be "picked" off the list with control-click ?
