The following restrictions apply to importing data into Minitab®; the PPM data must be adapted accordingly, if necessary.
Column names can be a maximum of 31 characters long.
For some analyses, it is necessary for the first eight characters of the column names to be unique. PPM displays a corresponding error message.
Column names must not contain the # and * characters.
The length of the column content is limited to 80 characters.
The format/type of a column is defined by the first value in the column. For example, if an A appears in the first row and the subsequent rows contain a figure, this column will be viewed as a text column in Minitab®.
In Minitab®, non-numerical values in numerical columns are replaced with the * character (symbol for zero values).
