You may encounter this error if a custom data element in Luminate Online has been mapped to a custom field in LCRM if the field in LO allows more characters than the field in LCRM. To resolve this issue:
  1. Increase the corresponding field length in LCRM
  2. Rebuild the QPM errors
In some cases it may not be possible to increase the field length in LCRM. In this case, the data will need to be truncated in Luminate Online. In particular, source codes or sub source codes may be too long if they were generated from an email subject line. Notify support when donations from that email send have tapered off and support can correct all of the donations at one time.
