SAP Note 26716 - CK11: Illegal_temporary_objnr during update

Symptom:

Product costing, transaction CK11 or CK64, terminates with the RAISE_EXCEPTION 'Illegal_temporary_objnr' as soon as you attempt to store the costing with cost element itemization.

Cause and prerequisites

A negative splitting was calculated for one of the materials costed. In this case, the respective cost element cost object is (incorrectly) not deleted, and it also has no final cost element itemization number. When updating, an attempt is made to update the cost object with the temporary number and the program terminates.

Solution
Repaired in 3.0B. To correct the error immediately, a repair to the function module CK_F_ASSEMBLY_COSTING is necessary. Please insert the lines marked with <<<<
