This is an OLE DB for OLAP property. Can be a combination of zero or more of the values described in the following table.
| Value | Meaning |
| MDPROPVAL_MD_BEFORE | The provider supports the flag BEFORE. |
| MDPROPVAL_MD_AFTER | The provider supports the flag AFTER. |
| MDPROPVAL_MD_SELF | The provider supports the flag SELF. This bit must be set by all providers because support for SELF is mandatory. |
