FMS - auto populate value in UDF

Hi, all

I wish to auto populate a value in UDF after I add the outgoing payment. This UDF will show DocEntry concatenate with DocDate. Scenario as below:

Outgoing payment doc entry is 105

Outgoing payment doc date is 24/01/2014

After I added this document, I want the outgoing payment UDF result show 10523/01/2014.

The concatenate query is : select RTRIM (DocEntry) +  CONVERT (varchar, DocDate, 103) from OVPM

May I khow how is this query apply and the value (10523/01/2014) is save in Outgoing payment?

Thank you.

Regards
