Example for BAPI_FUNCLOC_CHANGE with customer fields

Hello,

I want to use the function module BAPI_FUNCLOC_CHANGE in order to change a customer field that has already been created on the Table IFLOT. The parameter EXTENSIONIN has been added to the BAPI for that purpose, but unfortunatelly I cannot find the way to use it properly.

Furthermore, I would like to know how can I get the data neccesary for the Importing Parameters.

Could anyone provide me an example of its use?

Thank you in advance,
