Description

As we know, currently, if we select a date range to build the cube and
there is no data for this segment, the build process will fail due to no
values for the dictionary, however, image a frequent case that at the
beginning of a project, the data is prepared by other teams ONLY with the
latest several days or months, but we actually want to fill the data in the
cube from the beginning of 2 years ago and build the cube segment by
segment by each month, since lack of the previous old data of the earlier
months, currently, we have to produce some fake data with specified
requirement for the earlier months and build those segments, which
sometimes is really a hard,tired, and time-consuming work

thus, can we make the build process successful even though the data for
that month is empty, and just leave these segments empty, then, at the end
of the project, all the data may be ready, and we can "REFRESH" the earlier
months to fill the data~
