Create the required CDS view, activate it, and then create a behavior definition based on the CDS view:

```sql

@Semantics.user.createdBy: truekey holiday_id,@Semantics.user.lastChangedBy: truemonth_of_holiday,@Semantics.systemDateTime.createdAt: trueday_of_holiday,@Semantics.systemDateTime.lastChangedAt:truechangedat

```

This behavior definition is based on the CDS view for the previously created ZCAL_I_HOLIDAY_JERRY:

The behavior definition implementation code is as follows:

```abap

managed; // implementation in class zbp_cal_i_holiday_jerry unique;define behavior for ZCAL_I_HOLIDAY_JERRY alias holidayRootpersistent table ZCAL_HOLIDAY_001lock master/*This defines the root node as main locking object to avoid multiple persons editing the same object.Sub nodes have to be defined as lock dependent later on.*/// authorization master ( instance )//etag master { create; update; delete;}

```
