BAPI_SALESORDER_SIMULATE not working on similar lines as VA01

Hi All,

Thanks for reading the post.

  We have configured pricing condition for volume discount i.e. if the amount of SO is greater than X;  customer is given discount of y% on sales value.

  When we create sales order using VA01; pricing conditions are applied which includes volume discount say value P( p = y% of X).

   When we trigger BAPI_SALESORDER_SIMULATE with the same data; pricing conditions are applied but the pricing condition of volume discount is  showing as zero instead of P.

Regards,

Ganga
