When ALWNULL(*NO) is specified as a compile option, a data mapping error will occur if a record containing null values is retrieved from a file. When ALWNULL(*YES) is specified as a compile option, the data mapping error will not occur if a record containing null values is retrieved from an externally described input-only file (with no file addition) and the database default value is placed in a field containing a null value.
No recovery action is required.
