The error KS137 "Deletion not possible dependent records for CC exist in table COSR appears" is issued when trying to change the validity of Cost Center.

SAP S/4HANA Cloud Public Edition

Validity period changes can't be executed if there is still dependent data existing for the cost center in this fiscal year which are affected by the change.

As mentioned in the error message there is dependent data in the COSR table, this refers to Manage Statistical Key Figure data.
The standard behavior is that the statistical Key figure is fixated for the whole fiscal year once a posting is done of the year.
That's why the changes in validity period is not possible.

Consider blocking the validity period for postings and create new validity period from the year where there are no existing postings.
