Unable to edit the data in PSA

Hello Friends,

For last few days I am getting an process chain error due to invalid data in PSA. The error seems to be because of a trailing SPACE " " but I am not able to edit the data as no edit option is appearing. I have deleted the failed requests but still its not coming. I think there may some other related targets also. Is there any way to find the all the related target.

I have attached some screens as I am not sure of the cause, any help is appreciated.

Although this load failing but chain after it is running as normal and the corresponding reports are getting updated, I don't understand how it is possible and if really there is any impact ?

Thanks in advance..

Regards,

Sayantan
