Target Cost was zero in production order

Question

Hello,
We are experiencing every 1st day of the month target cost was zero for those production order which basic start date was on the 1st day of the month, this happen last march and this april it also happening but in january and february we did not experienced this issue. we wonder how this happening to us, since as we check those production order which basic start date was on the 2nd date and prior all has values in its target cost, this is for same finished material. How was this happening to our plant? how can we check and resolve this issue? am on a PP guy, as i have check the data of those order nothing peculiar for me, and it those material has cost estimate ok, this was released on the 01.01.2009 in this costing run will last untill of the year this was also been seen in the material master data current cost estimate.
As we have search for the performance assistant in SAP it thus tells us:
Total Target Costs
Total value of the target costs.
Calculated with the following formula:
Total target costs = Target cost debit + Target cost credit.
Use
Target costs are the planned costs adjusted to the actual operating rate.
The target debit on a manufacturing order is the sum of the activity-independent planned debit of the order and the activity-dependent planned debit of the order multiplied by the actual quantity of the order.
The target credit of a manufacturing order results from the goods receipt postings to stock. The delivered actual quantity is valuated with the planned price according to the price control.
The total value of the target costs is the sum of the target debit and the target credit.
The target costs are calculated during variance calculation and updated to the database.
The target costs cannot be shown until you have performed variance calculation for this target cost version. The target credit for the calculation of the total variances and production variances cannot be calculated until an actual quantity for an order exists after a goods receipt posting.
For the calculation of variances, the target costs are compared with the control costs.
Dependencies
The calculation of target costs depends on the selected target cost version.
But still we don't know how to check the issue and fixed it:
Please help us and guide us to resolve this issue
Thanks

Hi,
in some more details i have found out on our issue, one of the prerequisite for our variant calculation is Variance calculation at the manufacturing order level requires that the order is fully delivered (final confirmation is done) and technically completed ( except order pass through the mid night of period end ). Those informations can be displayed in the manufacturing order status.
order should be TECO right? but as said on this order pass through the mid night of period end can be have variance calculation, thus am right? this could be affect why the target cost was zero?
Thanks
