I am trying to copy characteristics from one material to another. I am using 1st option in tcode CLMM. My source material has multiple values assigned for the selected characteristic. However after mass change, only one value is assigned in target material. Also the log is showing an error message "Characteristic &1: Additional operation for generic change not allowed".

Can someone help me to solve this error?

The 'Additional operation for generic change not allowed' error usually occurs when the target object already has values assigned in material classification (Please see MM02 -> 'Classification View' of target object) . Therefore, before copying assigned values, in the 'Target objs' tab (in transaction CLMM) the option 'Overwrite Existing Values' must be enabled.

The behaviour when multiple values are assigned to a characteristic (that are then copied to the target object) in CLMM has recently been documented on the Classification Wiki page:

Please refer to the sections 'Example: If target object is already classified' and 'Single versus Mulitple Value assignments'. Currently, the issue described is noted under 'Case 3' in the 'Single versus Mulitple Value assignments' section.

As mentioned, please make sure the option 'Overwrite Existing Values' is enabled before the values are copied in CLMM.

yes. Selecting the option 'Overwrite Existing Values' works.

Thank you!

Hello Ritesh,

Thank you for your response. yes I did refer to this document. However all characteristics values are not copied in target material. only one gets copied.
