S.C. Code § 15-39-130
The sheriff, coroner or other officer with whom final process shall be lodged shall, at each regular term of the court from which the execution or process was sued out, during the continuance of its active energy, until full execution thereof be returned, make a return to the office of the clerk of the court of common pleas of his actions and doings thereunder. If he shall have fully executed he shall return the process with the manner of its execution. If he shall have partially executed he shall return on oath to the clerk a statement in writing under his hand of such partial execution with the reason of his failure as to the remainder. If he shall have wholly failed to make execution he shall return on oath a statement in writing under his hand of his failure with the reasons. And in any event on the first day of the term at which the active energy of the process shall cease as provided by law he shall return the process, if it has not been before returned, as fully executed. The return of the officer made as aforesaid shall for all purposes have the same legal effect as if the process had been made returnable to the term succeeding its first lodgment and renewed after each subsequent regular term.
