Applications for Period &0T_YESES& ?

Hello all,

I have seen a lot of res. key figures (RKF)delivered by SAP in this format like, does this type of naming convention tell you something or is it kinda indication, i am looking at a SAP delivered query and there are two RKF with exactly the same names "Applications for Period &0T_YESES&"

Can someone explain what does this mean?

Thanks
