Adding additional fields to products - Sage 50 Quantum 2019

Hi,

i need addtionial fields in the inventory, the currently available count of 12 has reached out.

Is there a way to achieve this ?

i already added a field FLD13 to sg_auf_artikel (Main article table) and the corresponding header text to sg_sys_objektdaten, but it doesn't work.

i also added the FLD13 to file GSMandant.xml, stored where the clients data is stored.

How can i do this ?

The best would be an own tab with checkboxes and such, but an additional text field would be great to know if it is working at all.

Thanks
