The Purchase / Sales Post Codeunit contains a number of checks that are performed before the document can be posted.

Depending on the customer's process, it may be necessary to check the document before posting, e.g. before release.

However, the functions for checking are all in the local scope of the codeunit.

A good idea would be to move this check to a global scope or a new codeunit, so that the checks could be used already before posting.

Currently this is only possible if the standard code is copied and outsourced as a custom function.

A check before booking would still be a custom function, but it would be much easier to use this standard check. because the standard check functions are also maintained by the base app.
