Hi @Chun Kit Wan

You did not mention if you are using ETA Java or ETA C - but I can see you asked Java question previously...

I found an example of encoding a blank field in one of our example source code files Java\Eta\Applications\Examples\src\main\java\com\refinitiv\eta\examples\codec\FieldListCodec.java

/* Field Entry: encode entry as a blank Real primitive type */
/* populate & encode field entry with fieldId & dataType information for this field */
/* need to ensure that FieldEntry is appropriatley cleared */
/* clearing will ensure that encodedData is properly emptied */ 

fieldEntry.clear();
fieldEntry.fieldId(22); /* BID field */
fieldEntry.dataType(DataTypes.REAL);
/* void* parameter is passed in as null & encodedData is empty due to clearing */
if ((retVal = fieldEntry.encodeBlank(encIter)) < CodecReturnCodes.SUCCESS)
{
    System.out.printf("Error %s (%d) encountered with EncodeFieldEntry.  Error Text: %s\n",CodecReturnCodes.toString(retVal), retVal, CodecReturnCodes.info(retVal)); 
     return retVal;
}
System.out.printf("\t\tFID %d  Encoded Real as blank.\n", fieldEntry.fieldId());

You will also find a similar snippet using encodeBlank() in section 11.3.1.5 Encoding Example of the ETAJ_DevGuide.pdf which is supplied with the Elektron SDK Java file.

If you are using ETA C, then a similar snippet can be found in the TransportAPI_C_DevGuide.pdf section 11.3.1.6 Encoding Example
