Getting error while publishing a contarct to ECC

Hi ,

After adding the line item with Unit price 0$ instad of 0.00$ for one contarct  and  try to publish this to ECC.But I am geeting error as

\"Enter Net price" which gets returend from ECC side.

Now Once I change the Unit price to 1.00$ but still it is not getting published and throwing the same error. Which I think the system lost it's backtrack.

Could some one help me for this error and provide me the some feedback how could I republish that contarct by adding more line item?

Thanks
