In this post we are going to see how to display text total using oops alv in sap abap.
We had one requirement where we need to display Total text in ALV grid using oops concept. To achieve it we did following things:
- Added one extra field in the ALV output table and populated it with a constant value (This is nothing but the text that need to be displayed as Total text) for all the records.
- Hide this field in field catalog level
- Populated the sort table for ALV with this field and enable subtotal display for it.
- Hide total line display in ALV by passing appropriate value in the Layout structure.
As this extra field contains constant value for all the records so subtotal on it is equivalent to total for rest of the fields.
Ex:
Output table
| Extra Field | Field1 | Field2 | Field3 | Field4 |
| Total: | A | B | 10 | 10 |
| Total: | A | A | 10 | 10 |
| Total: | B | C | 10 | 10 |
| Total: | C | D | 10 | 10 |
Final Output in ALV after subtotal on Extra Field
| Field1 | Field2 | Field3 | Field4 |
| A | B | 10 | 10 |
| A | A | 10 | 10 |
| B | C | 10 | 10 |
| C | D | 10 | 10 |
| Total: | 40 | 40 |
