А есть ли ограницения в PivotTable и если есть то какие?
Limitations of PivotTables Should Be Avoided
You want to avoid some of the limitations of PivotTables in Excel.
PivotTables are interactive tables that quickly summarize, or cross-tabulate, large amounts of data. Within a PivotTable, you can rotate the rows and columns to see different summaries of the source data, filter the data by displaying different pages, or display the details for areas of interest.
The following limits apply to PivotTables:
• Maximum size: There is no fixed maximum size. The size is usually limited only by the amount of available memory on your computer.
• Column fields: The product of the number of items in all column fields in a PivotTable cannot exceed 32,768.
Suppose that you create a PivotTable that contains five column fields. The fields contain 10, 5, 2, 40, and 3 items, respectively. The product of these values is 10 x 5 x 2 x 40 x 3, or 12,000. If you try to add one more field that contains three items, the product would be 12,000 x 3, or 36,000. Because this number exceeds the maximum product of the items, you see the following error message:
Not enough memory to completely display PivotTable.
Note that worksheets in Excel are limited to 256 columns. Therefore, even if you are successful in creating a PivotTable that contains a large number of column fields, you might not be able to display the entire expanded PivotTable.
• Row fields: The product of the number of items in all row fields in a PivotTable cannot exceed 2^31 (2 raised to the 31st power), or approximately 2.1 billion items.
• The same logic that applies to column fields also applies to row fields.
• Maximum number of records: There is no fixed maximum number of records you can use when you create a PivotTable.
In practice, creating a PivotTable from an external database that contains a very large number of records can strain the performance of the workstation on which Excel is running and can take a very long time to complete.
If you are creating a PivotTable from a very large database, you might want to use server page fields in your PivotTable.
• Maximum number of items per pivot field:
There is a limit of 8,000 unique items per row field, column field, or page field. If you try to drop into your PivotTable a field that exceeds this limit, the field will not be added to the PivotTable, and you might see the following warning message:
A field in your source data has more unique items than can be used in a PivotTable. Microsoft Excel may not be able to create the PivotTable or may create the PivotTable without the data from this field.
Solution
One way to avoid running into these limits is to use page fields in PivotTables, especially if fields contain more than 40 unique items. Using page fields makes your PivotTable more memory-efficient and reduces the size (in terms of cells) of the PivotTable. This feature makes the PivotTable easier to read.
Note: For more information about PivotTables, choose Microsoft Excel Help from the Help menu, type About PivotTable Reports: interactive data analysis in the Office Assistant or the Answer Wizard, and then click Search to view the topic.
