I have address field which is stored in accounts module while creating the account. Here what I want is this address field should reflect in all modules can any one clearly explain me about this query .thanks in advance.
--- You need to create the address field in all desired modules. (Copy address field defination from \cache\modules\Accounts\Accountvardefs.php and add in your module in upgrade safe manner Path \custom\Extension\modules\YourModule\Ext\Vardefs\yourAddressFied.php )
After this hit Quick Repair and Rebuild and see address field is created.
--- Secondly after adding field you need to show field in editviewdefs.php,detailviewdefs.php. (For this copy address field(billing,shipping) arrays from \modules\Accounts\metadata\editviewdefs.php ,\modules\Accounts\metadata\detailviewdefs.php and add in your module's edit/deailviewdefs.php in upgrade safe manner Path :custom/modules/YourModule/metadate/editORdeailviewdefs.php)
