ERP system approval is essentially a change in document status, and there is nothing difficult about it;
For example, when an Odoo14 customer requires that when a customer places a customized sales order, many departments within the company need to approve it before the customized product can be produced and the final sale completed.
The so-called approval is merely a permission block during the circulation of documents. Once the final confirmation step in the corresponding department is completed and the current department clicks confirm, the document will then flow to the next department for further approval.
For example:

A relatively convenient improvement is to assume that the approval is completed and directly convert the customized order detail products into a sales order through a certain action, so that the salesperson saves one instance of order entry work; it is even more convenient.
Currently we have implemented such a function.
