CLMM MASS UPDATE CLASS TYPE 013 Classification Controlling of production orders

[celine7744]

Hello
I need to mass update the characteristic values ​​for about 100 production orders. I tried to use CLMM as I usually use it to mass update  characteristics from  class type  for material . CLMM does not allow objects of class 013. Here is the error message returned.

I tried but I don't know how but I succeed once to have the authorisation for object type class 013 but I can't reproduce it

Is there a special setting to be made in CLMM to be able to modify the characteristics of class 013?If not, how can I mass modify the characteristic values ​​of several production orders?
