Diagnosis
The system could not calculate a price for the internal activity with activity type 20000 of cost
center 110TUP002 because none of the valuation strategies in valuation variant 006 was successful.
System Response
If the system issues a warning message or an information message, the costing item will be
used in costing with a value of zero.
If the system issues an error message, it sets the status "KF" (costed with errors).
If the system issues a termination message, the cost estimate cannot be processed.
Procedure
1. Check the master data for activity type 20000 of cost center 110TUP002.
2. If you have authorization for Customizing, check the valuation strategy for internal activities
in valuation variant 006.
Thanks&regards.

Hi,
For the orders for which you get the error, note the dates, then check in KSBT, whether there is price maintained for that period.
Eg: If the order has a start - 2nd Aug, 2010 & end 10th Aug, 2010, then check if price exists for period - 08, year - 2010

If the values are maintained, then check the costing variants specified for the order type in OPL8 for plant - order type combination in cost accounting tab. Then in OPL1, check the details specified for the variants. If you're not sure on this, take help from your FI-Co colleague.
