A data truncation error occurs when incoming data is too large to be stored. The error can occur for a number of reasons:
- In a Multi Select Picklist or Multi Checkbox field, the combination of selected values could be larger than the maximum storage size for the field.
- The default maximum size is 32 characters.
- If all values are selected, the number of characters required for N labels is the sum of the sizes of all N labels plus N-1 commas.
- That number can be reduced only if there are combinations of values that are never selected.
- In a single-selection Picklist, Global Picklist, or Dependent Picklist a value available for selection might be longer than the maximum storage size specified for the field.
- The combination of all fields defined in the record could be larger than the maximum size of a MySQL row (65,535 bytes).
