| # Moment of freezing estimates To specify the moment that estimates are frozen, use the Moment Freezing Estimates field in the Default Production Order Data (tisfc0102m000) session. When the estimates are frozen, every change on the order will result in variance postings, which increases database growth and makes system performance worse. You can select one of the following values, by number group or by production order series: Before First WIP Transaction During Releasing Order During Creating Order To improve performance, postpone estimate freezing as long as possible. Note that if you select Before First WIP Transaction, the estimates are calculated and stored at the first actual posting; this means that performance of the first step will not improve.
