Missing data: Profitab. Segmt No.

Hi

I am doing a Migration from 4.0b Version to ECC 6. Now my server is up with ECC 6 and have the datas for 4.0b. Order to cash cycle - I am not able to do a sales order. System is giving a message

Missing data: Profitab. Segmt No.

Message no. VU019

Missing data: WBS Element

Message no. VU019

But actually i have not enabled PS or COPA.. Not sure why this error occuring. I have Profit center accounting. All the customizing from 4.0b are copied in ECC 6. Kindly let me know if anybody has come across this problem and how it has been solved

Thanks in advance...
