Bound Action in Business Central

Limitation:

• As per Microsoft Bound actions cannot be added by extending an existing page that has been exposed as a web service.

Solution:

• Alternative I need to create one custom page with source table Sales Header.
• Need to add ODataKeyFields property for filter purpose.
• Need to create one procedure with ServiceEnabled property, after creating procedure we need to publish that page as web service. So, 3^rd party application will able to post sales invoice using our bound action.

Demo:

• Post Sales Invoice using POSTMAN.
