Power Platform Community Forum Thread Details

In Microsoft Dynamics 365 Project Operations (model-driven apps on Microsoft), this behavior is actually expected.

When you select multiple records from a grid and click a button, the system automatically falls back to the standard forms (Edit/Manager/Row Edit). It doesn’t open a custom form unless you explicitly tell it to.

So if your Mass Update button is opening the default forms, it’s usually because:

You’re using an out-of-box command like Open/Edit Selected
openForm() is called without specifying the formId
The custom form isn’t enabled for the app or security roles
Multi-select records aren’t being handled through custom JavaScript

What worked for me:

Create a ribbon button with JavaScript, collect the selected record IDs, and explicitly open your custom form by passing the form ID.

Example:

function openMassUpdateForm(primaryControl) {

    var grid = primaryControl.getGrid();

    var selectedRows = grid.getSelectedRows();

    var ids = [];

    selectedRows.forEach(function (row) {

        ids.push(row.getData().getEntity().getId().replace(/[{}]/g, ""));

});

    var pageInput = {

        entityName: "msdyn_approval",

        formId: "FORM_GUID"

};

    var parameters = {

        selectedIds: ids.join(",")

};

    Xrm.Navigation.openForm(pageInput, parameters);

This way, you fully control the navigation, and your custom mass update form opens instead of the default ones.

Hope this helps.

Thanks!
