Attribute change run issue (execute option is disabled)

Hi

I have a process chain which loads data Business Partner master data.

we have come across special character in a record which failed and we have rectified those issues.

Further to this data loading we have attribute chain .Since the process chain has failed we did manual

Loading of master data.we are not getting repeat/repair options.

Hence I think I need to do Attribute change run manually.

Problem while attribute change run manually

We have seen the info object is available in infoobject list.

As per the process we need to select the infoobject and execute.

But we can see the execute button is in disable mode.

Could you please suggest what necessary action need to take to do ACR. After this I need to execute further process chains.

Thanks & Regards
