Own - Customizing Table bcc / bco

Hi,

In our own built BO-component we need some CustomzingsTable (what we in SAP GUI did with SM31).

What is the best way to use this we have now created an BCO and BCC file in combi with a BAC file but seems not very stable.- are there any other ways to solve/set-up such things ?

Regards,

Jeroen Cosijnse
