With the SAP Exit processing type you can use variables delivered by SAP within BI Content.
Please note that you can use the variables provided by SAP only once they exist as an active version. You may have to activate these delivered variables before you can use them.
You can find the variables provided by SAP by searching for object type ELEM with subtype VAR. The technical names of delivered SAP objects always begin with a number.
If you want to define a query that only ever displays the data from the current month, drag the delivered variable current month (technical name 0CMONTH) for the characteristic calendar year/month (technical name 0CALMONTH) into the query filter.
Please note that the SAP Exit processing type is not possible with external SAP HANA views. The SAP HANA Exit processing type is available for this.
