欢迎来到 SO，user525552，

放松。你可以完全摆脱公式。将您的日期字段拖放到您的报告设计中，然后右键单击->格式字段->日期和时间并选择您喜欢的显示格式。

根据您的评论，试试这个公式。（我不相信你真的需要这个公式，但这确实回答了你的直接问题）

Monthname(
    month(
        DateAdd ("m", -4, {?Pm-Command.SCHED_END_DT})
    )
,true)

& "-" &

right(
    cstr(
        year(
            DateAdd ("m", -4, {?Pm-Command.SCHED_END_DT})
        )
    ,0,"")
,2)
