no wip and variance calcu error

I run KKAX for process order, it shows No WIP, Goods receipt 30 qty, but variance calculation KKS2 shows error, what should I do?

Only remaining var. in version 0 - no target costs for 001730600000

Message no. KV151

Diagnosis

For the calculation of variances with 001730600000 , the target costs in target cost version 0 are missing for the following reasons:

There were no planned costs and/or planned quantities (see earlier message).

The quantities on which the planned costs were based are zero in the time period concerned. This may be caused by the fact that no goods receipt for a cost object (such as a product cost collector or production order) has been entered.

This results in target costs of zero.

System Response

Because no target costs were calculated, the difference between the

planned and actual costs could not be broken down into variance categories. The difference is updated as a remaining variance.
