If you want to know how this works in on-premise using SQL management studio please review my older blogpost at: http://mileyja.blogspot.com/2008_09_01_archive.html.
There are some issues that arise out of using CRM Online as you cannot access the SQL Server your instance resides on, this means you cannot easily get the GUIDs you need from the backend unless you use web services to retrieve them. I know the metadata browser in 4.0 does not show the entitymap entity in the menu as entity you can drill down on, but believe me you can access this entity using a retrieve or retrievemultiple call using SOAP in jscript through the 2007 web services (which were also conveniently left in place for backward compatibility in CRM 2011). The other issue is that there is a minor change to the URL you need to use to access the custom mapping as CRM Online follows the IFD url structure for where the orgname is located.
1. First, you will need this jscript that you can attach to any entity form event in CRM to get the guid when that event is executed in order to retrieve the unique entitymapid for your organization to map from salesorderdetail (Order Product) to invoicedetail (Invoice Product). Since this only needs to be done once, you can just attach it to an event and use the preview form function to retrieve the GUIDs and then remove the jscript without ever publishing it.
First in 4.0 Online or On-Premise:
//create SOAP envelope
var xmlSoapHeader= "" +
"<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
"<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">";
var xmlAuthHeader = GenerateAuthenticationHeader();
var xmlSoapBody = "<soap:Body>" +
"<RetrieveMultiple xmlns=\"http://schemas.microsoft.com/crm/2007/WebServices\"> " +
" <query xmlns:q1=\"http://schemas.microsoft.com/crm/2006/Query\" xsi:type=\"q1:QueryByAttribute\" xmlns=\"http://schemas.microsoft.com/crm/2007/WebServices\">" +
" <q1:EntityName>entitymap</q1:EntityName>" +
" <q1:ColumnSet xsi:type=\"q1:ColumnSet\">" +
" <q1:Attributes>" +
" <q1:Attribute>entitymapid</q1:Attribute>" +
" <q1:Attribute>sourceentityname</q1:Attribute>" +
" <q1:Attribute>targetentityname</q1:Attribute>" +
" </q1:Attributes>" +
" </q1:ColumnSet>" +
" <q1:Attributes>" +
" <q1:Attribute>sourceentityname</q1:Attribute>" +
" </q1:Attributes>" +
" <q1:Values>"+
" <q1:Value xsi:type=\"xsd:string\">salesorderdetail</q1:Value>" +
" </q1:Values>" +
" </query>" +
" </RetrieveMultiple>" +
" </soap:Body>" +
"</soap:Envelope>" +
"";
var xmlt = xmlSoapHeader + xmlAuthHeader + xmlSoapBody;
var xmlHttpRequest = new ActiveXObject("Msxml2.XMLHTTP");
xmlHttpRequest.Open("POST", "/mscrmservices/2007/CrmService.asmx", false);
xmlHttpRequest.setRequestHeader("SOAPAction","http://schemas.microsoft.com/crm/2007/WebServices/RetrieveMultiple");
xmlHttpRequest.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
xmlHttpRequest.setRequestHeader("Content-Length", xmlt.length);
xmlHttpRequest.send(xmlt);
var resultXml = xmlHttpRequest.responseXML.xml;
alert(resultXml);
Now in CRM 2011 Online or On-Premise you can use the same script, but it must be encapsulated in a jscript library as a function that you call from the event:
function testfunc()
{
//create SOAP envelope
var xmlSoapHeader= "" +
"<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
"<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">";
var xmlAuthHeader = GenerateAuthenticationHeader();
var xmlSoapBody = "<soap:Body>" +
"<RetrieveMultiple xmlns=\"http://schemas.microsoft.com/crm/2007/WebServices\"> " +
" <query xmlns:q1=\"http://schemas.microsoft.com/crm/2006/Query\" xsi:type=\"q1:QueryByAttribute\" xmlns=\"http://schemas.microsoft.com/crm/2007/WebServices\">" +
" <q1:EntityName>entitymap</q1:EntityName>" +
" <q1:ColumnSet xsi:type=\"q1:ColumnSet\">" +
" <q1:Attributes>" +
" <q1:Attribute>entitymapid</q1:Attribute>" +
" <q1:Attribute>sourceentityname</q1:Attribute>" +
" <q1:Attribute>targetentityname</q1:Attribute>" +
" </q1:Attributes>" +
" </q1:ColumnSet>" +
" <q1:Attributes>" +
" <q1:Attribute>sourceentityname</q1:Attribute>" +
" </q1:Attributes>" +
" <q1:Values>"+
" <q1:Value xsi:type=\"xsd:string\">salesorderdetail</q1:Value>" +
" </q1:Values>" +
" </query>" +
" </RetrieveMultiple>" +
" </soap:Body>" +
"</soap:Envelope>" +
"";
var xmlt = xmlSoapHeader + xmlAuthHeader + xmlSoapBody;
var xmlHttpRequest = new ActiveXObject("Msxml2.XMLHTTP");
xmlHttpRequest.Open("POST", "/mscrmservices/2007/CrmService.asmx", false);
xmlHttpRequest.setRequestHeader("SOAPAction","http://schemas.microsoft.com/crm/2007/WebServices/RetrieveMultiple");
xmlHttpRequest.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
xmlHttpRequest.setRequestHeader("Content-Length", xmlt.length);
xmlHttpRequest.send(xmlt);
var resultXml = xmlHttpRequest.responseXML.xml;
alert(resultXml);
}
2. Now run the form event you attached the jscript to.
The alert message is a little bit difficult to look at when the script executes, but if you use fiddler to capture your sessions, it will show you the needed entitymapid GUID quite nicely:
3. Now you can piece together the URL for the mapping interface for the custom attribute mapping. The syntax to use is:
https://myorgsubdomain.crm.dynamics.com/Tools/SystemCustomization/Relationships/Mappings/mappingList.aspx?mappingId=entitymapidGUID
Here is a syntax example using the guid above:
https://myspecialcrminstance.crm.dynamics.com/Tools/SystemCustomization/Relationships/Mappings/mappingList.aspx?mappingId=EB562CC6-991B-DF11-87A9-02BF0A0679DE
NOTE: Since the GUIDs are unique to each organization of CRM, the GUID in the URL won't actually work except in my own personal organization.
4. Navigate to the URL using your browser and below is the resulting screen. You should see a similiar mapping dialog when you click "New" on the screen. I chose to show you the end result from 2011 in the following screenshot for the mapping screen, it looks only a bit different in 4.0 Online and functions the same way.
Thats all there is to it, just add you mappings as needed. If you need to get the other GUIDs for the other detail (product) entities in the sales process chain you just change the entity types in the script and re-run it.
