We are using Clarity version 15.4. We see there are differences in values of Cost in the slice table ODF_SSL_CST_DTL_COST and Clarity Cost plan details page. The slice table is not updating the values if any of the plan values are manually edited and then the plan is repopulated.
How cost plans populate was updated in 15.4 to allow for added functionality in the new UX.
This change was not allowing some records to be resliced when the plan was repopulated.
Reported as DE41635.
DE41635 is fixed in 15.5 and will be included in patch 18.104.22.168
