Unable to Implement Auto-Increment Numbering

Good day,



I'm trying to implement a Auto-increment numbering system for a column called "UsrClaimReqNum" inside a custom section.



I followed the instructions posted on this link - https://academy.creatio.com/documents/technic-sdk/7-13/how-add-auto-numbering-edit-page-field but I'm unable to get it to work.



I've set up two system settings "Claim Request Last Number" and Claim Code Mask" (Please find the pictures attached for both) and I've also added the following code on the edit page

    methods: {

            // Overriding Terrasoft.BasePageV2.onEntityInitialized base method, that 

            // is triggered when the initialization of the edit page object schema is finished.

            onEntityInitialized: function() {

                // onEntityInitialized method parent realization is called.

                this.callParent(arguments);

                // The code is generated only in case we create a new element or a copy of the existing element.

                if (this.isAddMode() || this.isCopyMode()) {

                    //  Call of the Terrasoft.BasePageV2.getIncrementCode base method, that generates the number 

                    // according to the previously set mask. 

                    this.getIncrementCode(function(response) {

                        

                    //    window.alert(response);

                        // The generated number is stored in [Code] column.

                        this.set("UsrClaimReqNum", response);

                    });

                }

            }

Is there something I'm doing incorrectly or should I be adding anything else?



Thank you in advance for your response & time.
