Business process fields Disable and FilterLookup in ms crm

Use the below way to disable the fields on BPF and it won't require "header_process_"  and it should work fine:

Xrm.Page.getAttribute("tk_typeofoffer").controls.forEach(function(control, index) { control.setDisabled(true); })

/Check if the control exist on the form

if (Xrm.Page.getControl(“header_process_parentcontactid”) != null) {

Xrm.Page.getControl(“header_process_parentcontactid”).setDisabled(true);

}

The same script you can use to apply to the header fields.

//Check if the control exist on the form

if (Xrm.Page.getControl(“header_leadsourcecode”) != null) {

Xrm.Page.getControl(“header_leadsourcecode”).setDisabled(true);

}

Below is a code snippet which will help you to filter a lookup:

function filterLookup() {

//Check if the control exist on the form

if (Xrm.Page.getControl(“header_process_parentcontactid”) != null) 

// add the event handler for PreSearch Event

Xrm.Page.getControl(“header_process_parentcontactid”).addPreSearch(addFilter);

}

}

function addFilter() {

var accountId = null;

var accountLookup;

var fetchQuery;

try {

//Check if control exist on form

if (Xrm.Page.getControl(“header_process_parentaccountid”) != null && Xrm.Page.getControl(“header_process_parentaccountid”).getAttribute().getValue() != null) {

//Get Account lookup value

accountLookup = Xrm.Page.getControl(“header_process_parentaccountid”).getAttribute().getValue();

//Get the account id

accountId = accountLookup[0].id;

}

//Build fetch

if (accountId != null || accountId != undefined) {

fetchQuery = “<filter type=’and’>” +“<condition attribute=’statecode’ operator=’eq’ value=’0′ />” +

“<condition attribute=’parentcustomerid’ operator=’eq’ value='” + accountId + “‘ />” +“</filter>”;

//add custom filter

Xrm.Page.getControl(“header_process_parentcontactid”).addCustomFilter(fetchQuery);

}

} 

catch (e) {

Xrm.Utility.alertDialog(“addFilter Error: ” + (e.description || e.message));

}

}

Get/Set Value

We need to use below method to get/set the value on the BPF fields.

Xrm.Page.getControl(“header_process_descriptions”).getAttribute().getValue();

Xrm.Page.getControl(“header_process_description”).getAttribute().setValue(“Hello World”);

If you want to write a script on the header fields then you can use below line of code for this.

Xrm.Page.getControl(“header_leadsourcecode”).getAttribute().setValue(parseInt(value));
