DMS - Additional Data: just „_“ is not accepted

Hi,

We want so store the value “_” (just an underscore) in a specific classification characteristic (Addnl Data) of DMS.

The characteristic is defined as CHAR (30), all values are allowed, no restrictions.

Seems that the characteristics do not accepted just an underscore as value.

whats the reason therefore?

Is there a solution to change that behavior?

Andreas.
