Hi, as you probably guessed I am new to Microsoft Dynamics.

I've been trying to add a filter on a lookup depending on the option you chose in an option set, but I can modify that option set both from the business process flow located in the header and from the body of my form.

I tried adding an OnChange function to the field located in the body of the form, but I'm not sure it applies to the (same) field located in the business process flow in the header. My code was working before, when I didn't use the business process flow as a way to select the option from the business process flow.

Do you know how to add an OnChange function to a field located in the business process flow?

I also tried using "header_process_" but I didn't success..

Here is the code I used before:

function OnChangeOfExpertType() {
Xrm.Page.getControl("rta_expertname").addPreSearch(function () {
addLookupFilter();
});
}

function addLookupFilter() {
var expertise = Xrm.Page.getAttribute("rta_experttype").getSelectedOption().value;
if (expertise != null) {
fetchXml = "<filter type='or'><condition attribute='new_typedelexpert' operator='eq' value='" + expertise + "' />"+
"<condition attribute='new_typedelexpert2' operator='eq' value='" + expertise + "' />"+
"<condition attribute='new_typedelexpert3' operator='eq' value='" + expertise + "' />"+
"<condition attribute='new_typedelexpert4' operator='eq' value='" + expertise + "' />"+
"</filter>";
Xrm.Page.getControl("rta_expertname").addCustomFilter(fetchXml);
}
}

PS: Sorry if my english is bad

Hello Vincent,

In regards to the onchange of a field on business process flow, you just need to add the event on the field present in the form body. When you change the field value on business process flow, the field on the body will change and the opposite occurs as well.

Therefore, it is not possible to add onchange event on the business process flow and the onchange event that you specify on the body field will work.

You just need to guarantee that the field is in the form body and has the onchange event.

Cheers!

Hi Vincent,

You can add field from bpf (for which you want to trigger jscript) on form as well and then trigger on change event of that field. If its not triggering then please check once if changing value of field in bpf changes value in field on form?

Hope this helps:)

Hi Vincent,

You need to maintain both header and body control in that case - try with this -

function OnChangeOfExpertType() { if (Xrm.Page.getControl("rta_expertname") != null && Xrm.Page.getControl("header_process_rta_expertname") != null) { Xrm.Page.getControl("rta_expertname").addPreSearch(function () { addLookupFilter(); }); Xrm.Page.getControl("header_process_rta_expertname").addPreSearch( function () { addLookupFilter(); }); } } function addLookupFilter() { var expertise = Xrm.Page.getAttribute("rta_experttype").getSelectedOption().value; if (expertise != null) { fetchXml = "<filter type='or'><condition attribute='new_typedelexpert' operator='eq' value='" + expertise + "' />" + "<condition attribute='new_typedelexpert2' operator='eq' value='" + expertise + "' />" + "<condition attribute='new_typedelexpert3' operator='eq' value='" + expertise + "' />" + "<condition attribute='new_typedelexpert4' operator='eq' value='" + expertise + "' />" + "</filter>"; Xrm.Page.getControl("rta_expertname").addCustomFilter(fetchXml); if (Xrm.Page.getControl("header_process_rta_expertname") != null && Xrm.Page.getControl("header_process_rta_expertname") != undefined) { Xrm.Page.getControl("header_process_rta_expertname").addCustomFilter(fetchXml); } } }

Hope this helps .
