Hello,
I am trying to use ETM to pull out the Acquired Date of an item, then set a custom Date field value based on this date. The custom field will be set to 49 months after the Acquire date.
Pulling out the value of the system field and doing the calculation is no issue, however when I try to set the value of the custom field, I am getting this error:

In this case, the “acquiredDate” variable is being set earlier in the mapper from outbound.self.acquiredDate.
If I convert the value to a string and use it to set the value on a single-line string field, it works fine (see below).

Any help would be appreciated.
Thanks,
Duncan
