# Number Server

## How to Combine Several Defined Variants within a Field

| ### What to do: |
| As a prerequisite to this example, you need to work through the example Integration of a number server. |
| Open the Mask Data from the context menu (right-click the desktop) Open > System > Masks or click the button . |
| Find the mask EDB-ART-CFR. |
| Click the tab Field Default. |
| Click the entry T_MASTER_DAT.PART_ID and click the button . |
| Change to the Default Value-M field and enter #ART-NR-1##ART-NR-3. |
| Note: There are 2 #s in the center part! Hash signs (#) act like brackets. The first hash sign defines the start of an enumeration circle, the second hash sign defines its end. A third hash sign would start a new enumeration circle etc. If you only use one hash sign in the center section, the following enumeration circle will be displayed as a fixed text. |
| Save the entry with the button . |
| Click the button Reconfigure at the top of the mask. |
| Call up the Item mask and create a few records. |
| When combining variants, both variants are incremented simultaneously. |
