Lock/Unlock Field on Form/BPF

By


There are 2 ways to Lock or Unlock the field on form:

1. Using Business Rule

Business Rule is simplest way to lock/unlock the field on form. It can be also used to show/Hide field on form or showing any error message on form or making field mandatory/non-mandatory.

Note: Business Rule can not work on fields present in Business Process Flow(BPF).

2. Using JavaScript : 

Following steps are used to lock/Unlock field on form: 

  • Use formContext object model
  • get control of field using formContext object model
  • use setDisabled property to lock/unlock the field
Syntax: 
           formContext.getControl(arg).setDisabled(bool);

arg: Schema name of field
bool: true for locking the field and false for unlocking the field

In order to Lock/Unlock the field in BPF, use "header_process_schemaname" as a argument.

eg. if First Name field with schema name as firstname is present in BPF and you have to lock the First Name field in BPF, then use following syntax: 
        
        formContext.getControl("header_process_firstname").setDisabled(true);

 In this blog we will see how we can use stored procedure to transform our data in ADF.  For better understanding you can check my previous blog for better understanding. When we integrate CRM data to external system SQL, then for  Option-Set fields present in CRM, we get Option-Set values and not Text value. eg. we have Credit Hold option set field in CRM and after integration we are getting option set value. To solve this problem we will create OptionSetMetaData table in SQL which will store details about option-set fields SQL query to create OptionSetMetaData table CREATE TABLE [dbo].[OptionSetMetadata]( [ID] [uniqueidentifier] NULL, [EntityName] [varchar](50) NULL, [OptionSetFieldName] [varchar](50) NULL, [OptionSetText] [varchar](50) NULL, [OptionSetValue] [int] NULL ) //To Insert Records in sql Table Insert Into OptionSetMetadata Values (NEWID(), 'account', 'Credit Hold', 'Yes', 1) Insert Into OptionSetMetadata Values (NEWID(), 'account...
