Hi Sid,
Please check below configuration -
IMG -> Public Sector Management -> Social Services -> Net Calculation -> Defien Control Paramters for Net Calculation
Please chek if the entry of Switch Value ID BGRFC_DEST is mainatined or not. If no, then make an entry and put option value as <ERP system>CLNT<ERP Client>BGXML.
Hope it helps, let me know how you go.
Thanks
