AP Invoice Posting via DI Server provides error 4002 define number series

When trying to post an AP invoice via DI Server an error is returned stating "to generate this document first define the numbering series in administration.

We have checked all areas whihc include:

Authorisations and our user is super user and has full authorisations to all series and groups series

Have checked Journal number series to validate number start, last and next sequence

Validated posting period and posting period indicators

When we try to create an AP Invoice within the UI logged in as the same user we are not presented with any errors at all.

Any ideas on the cause of this error?

Thank you
