Billing document not released to COPA

Hi All,

I have created a billing document and in VF02 i tried to release the document for accounting but it is giving an error message <b>""Check Value field assignment for condition ZRA1""

</b>

i checked the condition type assignment for SD in the Profitability Analysis (transfer of sale and billing orders),value field assignment and quantity field assignment is made correctly.

please suggest me where i am missing?

Thanks in advance,

Vijay Reddy.
