Improve Filters in "External Production-Collective purchase order" window

Hi,

We would really appreciate an improvement in the filter criteria in this window. For instance, when filtering by Doc Number you can apply the following options:

• equals to
• Bigger than
• smaller than

However, it is not possible to add a "in addition filter by" criteria. Meaning we are not being able to filter doc numbers between two diffrent numbers, just bigger than or smaller than.

Thanks in advance,

Julieta
