Regd table and field for the operation level maint activity type.

Hi

I have activated operation level costing and could see maint activity type (Not costing related activity type) at operation level.

Now we have one field maint activity type at header level and one more at each operation level through account assignment TAB

The difficulty here is I am unable to find out the table and field for the operation level maint activity type, Can you please advice on this.

Thanks & Regards
