Update not allowed after purchase order is created

Hi ​@nurfatin,

Please check Purchase Order Authorisation Rule setting. Whether changes are allowed after Authorisation (attached Purchase Order has been authorised). 

Have to create a Purchase Order Change Order for desired updates in Purchase Order if changes are not allowed after authorisation.

Please check debug console whether any Custom Event is getting triggered with mentioned error.

yup.. The one I attached is from change order. after that change order is authorized, usually need to update the Purchase Order. after click that one, this error message appeared

after click OK, this error message appear

Seems to be a Custom Event then. Please check Custom Events configured for PurchaseOrder entity.
