Now my requirement is update material classification.
Using bapi 'BAPI_OBJCL_CREATE' to create class and characteristic value for given material. But again i am using same material and same class and different characteristic value it is showing error message 'Assignment exists and is valid' .
Any one tell me bapi to insert new characteristic value for existing class in material classification.
I also tried bapi 'BAPI_OBJCL_CHANGE' it is overwriting existing characteristic value in material classification for given class.
Appreciate your help!!
