Party List :
- Party List is a data type in CRM, using which you can set more than one records of an entity for a single field.
- Party List type field, renders as Lookup on the form, but it works as multi select lookup.
- We can’t create a custom party list fields.
Function to set Call To in a Phone Call Activity (tested on CRM 2015 Update 1 Online):
function setCallTo() { debugger; var callTo = getAttr("to"); //Party list to set var callToArry = new Array(); callToArry[0] = new Object(); callToArry[0].id = getLkpId("new_calltocontact"); callToArry[0].name = getLkpName("new_calltocontact"); callToArry[0].entityType = "contact"; callTo.setValue(callToArry); } function getAttr(attributeId) { return Xrm.Page.getAttribute(attributeId); } function getVal(attributeId) { try { return Xrm.Page.getAttribute(attributeId).getValue(); } catch (e) { alert("getVal: Error for attribute " + attributeId); } } function getLkpName(attributeId) { return getVal(attributeId)[0].name; } function getLkpId(attributeId) { return getVal(attributeId)[0].id; }
