I am facing some problem during generation of billing through service order. I am doing following activities in sequence
1) Creation of Service order (SM02) with some service product.
2) Generation of reservation for material requirement (ERSA) from service order.
3) MIGO for material.
4) Actual cost displayed in order.
5) Creation of billing request from DP90.
In DP 90 if I am going through Sales Price Tab, it is showing the qty of ERSA material which I have withdrawn but not showing cost. If I am going on Expences tab, it is showing the cost of material withdrawn with qty. and the billed amount column is empety but if I put some figures in to be billed amount column and try to save the document, it emmits a message " Material-- not defined for sales organisation---".
Please suggest what should I do? I have already configured DIP profile for sales order.
Thanks in advance.
