give me the corresponding filter expression for the below statement which should validate in sap datasphere opn_stk_mnth = (Current date, YYYYMM) without format function as we don't have that in sap datasphere

In SAP Datasphere (formerly known as SAP Data Warehouse Cloud), you can create expressions to filter data based on certain conditions. If you want to filter for entries where `opn_stk_mnth` corresponds to the current date in the `YYYYMM` format, you might not have access to a `FORMAT` function. However, you can use the `CURRENT_DATE` function, extract the year and month, and concatenate them. Here's how you can construct the filter expression in SAP Datasphere: 1. Extract the year and month from `CURRENT_DATE`. 2. Concatenate them to form the `YYYYMM` string. The filter expression would look something like this: ```sql opn_stk_mnth = CONCAT(YEAR(CURRENT_DATE), LPAD(MONTH(CURRENT_DATE), 2, '0')) ``` ### Explanation: - `CURRENT_DATE` retrieves the current date. - `YEAR(CURRENT_DATE)` extracts the year part. - `MONTH(CURRENT_DATE)` extracts the month part. - `LPAD(MONTH(CURRENT_DATE), 2, '0')` ensures the month is padded with a leading zero if it's a single-digit month (e.g., January as '01'). - `CONCAT(...)` combines the year and the padded month to form a string in the format `YYYYMM`. You can use this expression in your dataset filtering to validate against the `opn_stk_mnth` field.
