What causes this issue?

If you change the <DS:GlOS.costing_variant>costing variant</> for the
<DS:GLOS.preliminary_costing>preliminary cost estimate</> of the
<DS:GLOS.product_cost_collector>product cost collector</> after the
affected product cost collector has already been posted to, this may
result in the following problems in the calculation of
<DS:GLOS.work_in_process>work in process</>, variances, and scrap:
You might not be able to repeat previous calculations of
<DS:GLOS.WIP_calculation>WIP</> and scrap because the valuation basis
is missing (cost estimate).
See also: <DS:SIMG.SIMG_ORKKBEWWIPPER>Valuation variant for work in
process and scrap</>
In variance calculation, discrepancies might result if the activity
confirmation in repetitive manufacturing is made on the basis of the
preliminary cost estimate for the product cost collector.
