hi rao,
from flat file remove netvalue2 to net value 12.store all net values under netvalue1 and try to load if possible.
When maintained 12 columns for key figure on excel and same used in dso also like 12 kf(mapped). am not sure by using any abap code possible or not. if possible then you need to use one keyfig in dso and need fill tht column by code.
flat file format not changeable?flat file out put was generated by any program?
Thanks
