Can not use rankOrderType within @RANK on PBCS

Summary:

Can not use rankOrderType within @RANK on PBCS

Content (please ensure you mask any confidential information):

This is Syntax of @RANK (rankOrderType, SKIPNONE | SKIPMISSING | SKIPZERO | SKIPBOTH, value, XrangeList)

But I can not use rankOrderType within @RANK on PBCS.

I found that this function result is: @RANK(SKIPNONE | SKIPMISSING | SKIPZERO | SKIPBOTH, value, expList)

Is this an error in the system?
