Restrict the sales order creation if the sales team is empty

Requirement

While creating a sales order, if the sales team is empty, then show a pop-up message to notify that the sales team is empty and doesn’t allow the creation of a Sales Order record.

Solution

Create a client script and check if the sales team is empty in the Sales Order record. If the sales team is empty, then show a pop-up message and it will not allow the creation of a sales order.

/**
 * @NApiVersion 2.x
 * @NScriptType ClientScript
 * @NModuleScope SameAccount
 */
define(['N/currentRecord'],
/**
 * @param{currentRecord} currentRecord
 */
function(currentRecord) {
    
    /**
     * Function to be executed after page is initialized.
     *
     * @param {Object} scriptContext
     * @param {Record} scriptContext.currentRecord - Current form record
     * @param {string} scriptContext.mode - The mode in which the record is being accessed (create, copy, or edit)

    /**

     *
     * @param {Object} scriptContext
     * @param {Record} scriptContext.currentRecord - Current form record

    function saveRecord(scriptContext) {
        try{
            var currentRec=scriptContext.currentRecord

            var sublistCount=currentRec.getLineCount({
                sublistId:"salesteam"
            })
          
            if(sublistCount<1){
                alert("Please enter a value for the sales team")
                return false
            }
            return true
        }
       catch (e) {
           console.log("error@saveRecord",e)
       }

    }

    return {
        saveRecord: saveRecord
    };
    
});
