Attachments and Notes Locked

 Hello,

Here is an example on how to achieve this in opportunity page:

1) Add the boolean column in the Opportunity edit page. The code for the column should be "UsrInactiveStatus". Save this change.

2) Create a business process that will set the value to true or false in case the status of the opportunity is either active or inactive (use "record modified" trigger signal which triggers on the opportunity modification in the "Stage" column (be careful not to cycle the business process, it's as a must to select the "Stage" column as a column that triggers the process)). Also at the end of the process execution it should refresh the current opporutnity page (use this marketplace app to achive this task).

3) Create a replacing view model for the "FileDetailV2" module and add the following code to the module:

define("FileDetailV2", [], function() {
	return {
		mixins: {},
		properties: {},
		attributes: {},
		messages: {},
		methods: {
			upload: function(config, callback) {
				var isOpportunityAttachment = config.entitySchemaName == "OpportunityFile";
				var canUploadFile = this.getIsCurrentStatusActive();
				if (isOpportunityAttachment && canUploadFile) {
					this.callParent(arguments);
				} else {
					Terrasoft.showErrorMessage("Current status is inactive, uploading restricted");
				}
			},
			getIsCurrentStatusActive: function() {
				var columnsValuesObject = this.sandbox.publish("GetColumnsValues", ["UsrInactiveStatus"], [this.sandbox.id]) || {};
				return columnsValuesObject.UsrInactiveStatus;
			},
		},
		diff: /**SCHEMA_DIFF*/[]
		/**SCHEMA_DIFF*/
	};
});

4) Refresh the page and chek the result.

As a result in case the value for the UsrInactiveStatus column is false, the upload method will return an error popup stating that the current stage is inactive and uploading files is restricted. You can also check it by displaying the UsrInactiveStatus checkbox on the page and enabling\disabling it (an opportunity record must be saved each time you enable to disable the checkbox).
