SPR 816187 exists because of this limitation. I had to use the %user%-%date% into one variable to get around it. Contact your VAR to attach you to this SPR.
It is not possible to capture user and date participating in parallel approval into separate variables using Mapped Approver option
Open Customers need to capture who particiapted in an approval and when the approval was performed. In order to search/sort etc. the drawing data card normally has an "Approved by" and "Approved date" field. The intent of the Mapped Approvers functionality was to be able to write into the data card who particpated in an approval if multiple users are involved, not just the last approver that triggers the transition. This works ok provided you only need the username and no separate date - but it is not possible to capture both name and date into separate variables. That leads to values being skipped. You can write user AND date into same target variable (%user%-%date%) but this restricts you from searching, sorting etc since it becomes a string and cannot be handled as date.
Thanks Steve. That's not what I wanted to hear but it is what I expected. Guess I'll have to keep my fingers crossed for this to be corrected.
