how can i apply where condition for the below statement which should validate in sap datasphere graphical view opn_stk_mnth = (Current date, YYYYMM)
To apply a WHERE condition in a SAP Datasphere graphical view to filter data based on the current date formatted as YYYYMM, you can follow these steps:
1. **Add a Filter Node**: In the graphical modeling interface, introduce a filter node after the node where your data (e.g., `opn_stk_mnth`) originates.
2. **Define the Filter Condition**:
1. Click on the filter node you just added.
2. In the properties pane, you can define the filter condition.
3. You'll typically want to use a calculation or formula to compare your `opn_stk_mnth` field to the current date in the YYYYMM format.
3. **Using Current Date**: To fetch the current month in the format you need (YYYYMM), you'll need to use a function that formats the current date correctly. This is often done using a combination of the `CURRENT_DATE` function along with formatting functions available within SAP Datasphere.
4. **Example of Filter Condition**: You will generally use a condition like this, where `opn_stk_mnth` is compared to the formatted current date:
```sql
opn_stk_mnth = TO_VARCHAR(CURRENT_DATE, 'YYYYMM')
```
Note: The actual syntax for functions and how dates are manipulated can vary in different versions, so you might also see variations like `FORMAT_DATE(CURRENT_DATE, 'YYYYMM')`.
5. **Ensure Data Types Match**: Confirm that the `opn_stk_mnth` field is compatible with the format you're extracting. If it’s stored as a numeric or string type, ensure the comparison is appropriately cast if necessary.
6. **Test Your Query**: After applying the filter, validate the condition to make sure it correctly limits your results to only those entries that match the current month.
By following these steps, you should be able to successfully implement a WHERE condition that filters based on the current month in YYYYMM format in your SAP Datasphere graphical view.
