Zero records converted in RMCA9155

Hi Experts,

I am trying to execute program RMCA9155 for MPS process, to Copy and Delete version 000 to a Week

Source info structure           S901

Source version                  000

Target info structure           S901

Target version                  601

No copy method

Do not copy initial records

On executing, I get message as zero records converted.

what is the purpose of RMCA9155 program. will this program copy & delete at the same time. If so what it copies & what it deletes. if I want to get the message as converted successfully some records, what is the pre requisite?

Thanks

Sakthi
