CustomFields.ReadCustomFieldsByMdPropUids Method

Gets the custom field definitions for the specified custom field unique identifiers.

Namespace:  [CustomFields Web service]
Service reference: http://ServerName:32843/[Project Service Application GUID]/PSI/CustomFields.svc
Web service reference: http://ServerName/ProjectServerName/_vti_bin/PSI/CustomFields.asmx?wsdl

[SoapDocumentMethodAttribute("http://schemas.microsoft.com/office/project/server/webservices/CustomFields/ReadCustomFieldsByMdPropUids", RequestNamespace = "http://schemas.microsoft.com/office/project/server/webservices/CustomFields/", 
	ResponseNamespace = "http://schemas.microsoft.com/office/project/server/webservices/CustomFields/", 
	Use = SoapBindingUse.Literal, ParameterStyle = SoapParameterStyle.Wrapped)]
public CustomFieldDataSet ReadCustomFieldsByMdPropUids(
	Guid[] md_prop_uids,
	bool autoCheckOut
)

Parameters

md_prop_uids
Type: []
An array of custom field GUIDs
autoCheckOut
Type: System.Boolean
If true, check out the custom fields for modification.

TipTip

The ReadCustomFieldsByMdPropUids method ignores the locale setting of the computer running Project Server. The ReadCustomFieldsByMdPropUids2([], Boolean) method returns a CustomFieldDataSet that includes locale-dependent values for formulas that calculate custom fields and graphical indicators.

The following example uses ReadCustomFieldsByMdPropUids and ReadCustomFieldsByMdPropUids2 to read a custom field, and then writes the customFieldDS contents to CustomFieldDataSet.xml and CustomFieldDataSet2.xml, respectively. Except for MD_PROP_FORMULA, the two methods return the same data.

For more information, including a procedure that shows how to use Project Web App and Project Professional 2010 with the same formula, see Using Formulas and Graphical Indicators with Custom Fields.

The formula field MD_PROP_FORMULA that is returned by ReadCustomFieldsByMdPropUids depends on the locale (the language of the server and the Project installation). Following is the formula field MD_PROP_FORMULA that is returned by ReadCustomFieldsByMdPropUids.

<MD_PROP_FORMULA>Switch(Not ([MSPJ188743724] &gt;= #01/01/1984# And [MSPJ188743724] &lt; #01/01/2050#), 
"No Baseline", ([MSPJ188743685] + 1) / ([MSPJ188743686] + 1) &gt; 1.2, "Overbudget by 20% or more", 
([MSPJ188743685] + 1) / ([MSPJ188743686] + 1) &gt; 1, "Overbudget", True, "Under budget")</MD_PROP_FORMULA>

The formula field MD_PROP_FORMULA that is returned by ReadCustomFieldsByMdPropUids2 (as shown in the following code) is independent of locale. It works the same way on different language installations. For this reason, the ReadCustomFieldsByMdPropUids2 method is preferred over the ReadCustomFieldsByMdPropUids method.

<MD_PROP_FORMULA><MD_PROP_FORMULA>Switch(Not ([Baseline Estimated Finish] &gt;= #1/1/1984# And [Baseline Estimated Finish] &lt; #1/1/2050#), 
"No Baseline", ([Cost] + 1) / ([Baseline Cost] + 1) &gt; 1.2, "Overbudget by 20% or more", 
([Cost] + 1) / ([Baseline Cost] + 1) &gt; 1, "Overbudget", True, "Under budget")</MD_PROP_FORMULA>

Furthermore, the example modifies the formula and calls the UpdateCustomFields2 method to update the custom field, and then writes the updated dataset to UpdatedCustomFieldData.xml

It calls the CheckInCustomFields to check in the custom field after modification, and calls the CheckOutCustomFields to check out the custom fields before modifying them.

The example uses the SvcCustomFields namespace in the ProjectServerServices.dll proxy assembly. The ConfigClientEndpoints method and the SetClientEndpoints method use an app.config file for setting the WCF binding, behavior, and endpoint. For information about creating a PSI proxy assembly and an app.config file, see Prerequisites for WCF-Based Code Samples.
