FPM - Error in context

Hello,

I use MDG-S and I have extended BP model. I have added others entities, I have a problem when I saved data in database.

I have create a new configuration ZO_BS_BP_GEON by webdynpro FPM_LIST_UIBB.

I have create a new class ZCL_BS_BP_GUIBB_GEON_LIST, where the superclass is CL_BS_BP_GUIBB_LIST.

The class ZCL_BS_BP_GUIBB_GEON_LIST has the interfases:

I have redefinied the method IF_FPM_GUIBB_LIST~GET_DEFINITION

EO_FIELD_CATALOG ?= CL_ABAP_TABLEDESCR=>DESCRIBE_BY_DATA( MT_GEON ).

And the method IF_FPM_GUIBB_LIST~GET_DATA. I have insert lines in ct_data.

In new configuration ZO_BS_BP_GEON I have change the feeder class and I have assigned the class ZCL_BS_BP_GUIBB_GEON_LIST.

The system display an errors of the field propieties but I can save changes

When I create a new supplier in NWBC and I added a new line in the POWL of the configuration ZO_BS_BP_GEON, the system dysplay a dump.

Could I modify the feeder class by a Z feeder class? I need to save the data in database tables Was this the method to do it?

Thanks!
