i guess it is not as simple as this , i want to add a field (back end and front end in a choice list may be) beside every field : one beside NPI load , one beside TPM load , one beside RE load and one beside RED load so the user can chose either this load is for a front end or back end
that's mean that the back/front end and the load field must be linked (exemple : this NPI load is for a back end )
NB : the field are in a repeating table
