BI-IP:Derived characteristic overwritten again within copy planningfunctio

I have an issue using planning function "copy". I am using this planning function to copy my planned data within the real time infocube chaning the plan version from 1 to 2 within my realtime infocube. In my realtime infocube, i have a characteristic relationship to derive the date, time and user and unique id for each record. However, when I try to copy those records now into a new version, I get the following error messages:

Errors while executing sequence copy cylce 1 to cycle 2.

Planning functioncopy cycle 1 to cycle2 ended with errors

Critical error during characteristic derivation

Derived characteristic overwritten again

Characteristic 'zinscomp': Old value ' ', new value ' c '

Critical error during characteristic derivation

Derived characteristic overwritten again

Characteristic 'zinscomp': Old value ' ', new value ' c '

Any Idea how to solve this issue?

Following steps i tried :

Here I have user entry for Insertion compenent of a material.

so I check the Status of Insertion compenent of material In material master data with data in the planning cube.

I got 2 mismatch in the staus for material and corrected in material master.

After doing this task also i am getting the same issue .

Kindly propose some suggestion how to proceed ?
