[ISO/IEC 29500-1 1st Edition]

18.10.1.90 sharedItems (Shared Items)

Represents the collection of unique items for a field in the PivotCacheDefinition. The sharedItems complex type stores data type and formatting information about the data in a field. Items in the PivotCacheDefinition can be shared in order to reduce the redundancy of those values that are referenced in multiple places across all the PivotTable parts. [Example: A value might be part of a filter, it might appear on a row or column axis, and will appear in the pivotCacheRecords definition as well. However, because of the performance cost of creating the optimized shared items, items are only shared if they are actually in use in the PivotTable. Therefore, depending on user actions on the PivotTable layout, the pivotCacheDefinition and underlying PivotCacheRecords part can be updated. end example]

If there are no shared items, then field values are stored directly in the pivotCacheRecords part.

[Example:

<sharedItems count="1">
<s v="[Customer].[Customer Geography].[Country].&amp;[United States]"
c="United States"/>
</sharedItems>

end example]

The following attributes are not required or used if there are no items in sharedItems.

  • containsBlank

  • containsSemiMixedTypes

  • containsMixedTypes

  • longText

The following attributes are not used unless there is more than one item in sharedItems or the one and only item is not a blank item. If the first item is a blank item the data type the field cannot be verified.

  • containsNumber

  • containsDates

  • containsString

  • containsInteger

The following attributes can be omitted without loss of functionality.

  • containsNonDate

  • count

The following attributes are not required and can be omitted. However, refreshing the PivotTable could produce different groupings than before.

  • maxDate

  • minDate

  • maxValue

  • minValue

Applications should ensure that “date” attributes are not mixed with “value” attributes.

A value of 0 or false indicates non-integer or mixed values.

The possible values for this attribute are defined by the W3C XML Schema boolean datatype.

containsMixedTypes (Contains Mixed Data Types)

Specifies a boolean value that indicates whether this field contains more than one data type.

A value of 1 or true indicates this field contains more than one data type.

A value of 0 or false indicates contains only one data type. The field can still contain blank values.

The possible values for this attribute are defined by the W3C XML Schema boolean datatype.

containsNonDate (Contains Non Date)

Specifies a boolean value that indicates that the field contains at least one value that is not a date.

Specifies a boolean value that indicates that this field contains text values. The field can also contain a mix of other data type and blank values.

A value of 1 or true indicates at least one text value, and can also contain a mix of other data types and blank values.

A value of 0 or false indicates the field does not have a mix of text and other values.
