Variances in CO03

Hi experts,

There are some Production Orders which were settled through co88. All these production orders are for semi-finished products. Whne we run Co88 the production variance is going and sitting in PRD-PRF A/c(In val.class xxxx - SFgoods). When i check the production order co03>goto>cost analysis>

cost element-xxxxxxxxx(change in work in process)

Origin-nothing is there

totat target costs: 0.00

total actual costs:1000

target/actual var: 1000

t/I var % ; (nothing is here)

the same diff 1000 is going and sitting in production variance account. (PRD-PRF-VAL CLASS-XXXX(SFG).

But there is not much diff between actual/target(

0.02 paise only) all together.

Why the amount 1000 only is going to production variance account?

Please clarify. thanks in advance
