Hi Raghav,
It says "/PLMU/CL_FRW_G_FEEDER does not contain an interface IF_FPM_GUIBB_FORM.
The class name which i started working on initially is CL_MDG_BS_MAT_FEEDER_FORM_SET.
And inside this class there is a method called GET_DATA. This Method is in the class /PLMU/CL_FRW_G_FEEDER_FORM.
Here I enhanced the using implicit enhancements. Please help now
