Which Mfg/pro version you are using ?
socrshp.p is responsible program to create the shp_hist table. But i think this will only create when you are using the PRo/Plus module. Please verify if you have installed pro/Plus in your verion.
I think socrshp.p is introduced after version eB S4 , and you cannot find it in prior version.
This field only used in performance calculation , so this is not stoed in ih_hist.
