Data Files Not Created from Multiple Tables (OMS command)

If any tables do not have the same number of row elements as the other tables, no data file will be created. The number of rows doesn't have to be the same; the number of row elements that become variables in the data file must be the same.

For example, a two-variable crosstabulation and a three-variable crosstabulation from CROSSTABS contain different numbers of row elements, since the "layer" variable is actually nested within the row variable in the default three-variable crosstabulation display.

In general, the less specific the subtype selection in the OMS command, the less likely you are to get sensible data files, or any data files at all. For example:

OMS /SELECT TABLES /DESTINATION FORMAT=SAV OUTFILE='mydata.sav'.

will probably fail to create a data file more often than not, since it will select all tables, including Notes tables, which have a table structure that is incompatible with most other table types.
