SALV Table 11 – Apply Aggregations

Apply Aggregations like Totals, Minimum values to SALV Table

In the series of the SALV Model Table display in SAP ABAP, today we will see how to apply aggregations to the ALV Grid. You can find all the Previous discussion at Tutorials > SALV Table Display .

Aggregations plays important role in the reporting. E.g. Providing the TOTALS, Minimum values, Maximum values, Subtotals etc. To achieve this in the SALV model, we have the class CL_SALV_AGGREGATIONS.

For instance, to apply TOTALS on the the NETWR column (as shown in the example) we need to use the method ADD_AGGREGATION on this column. The parameter AGGREGATION would be used to determine the type of the aggregation. Interface IF_SALV_C_AGGREGATION contains the constants which can be used in this parameter.

In this example I need to change the output table to add column NETWR as compared to previous discussion in this series, so I will provide the entire code which generate the output which has all three scenario. For test purpose, We will apply TOTALS on the NETWR column. Once the TOTAL is applied, we will bring the TOTAL row at the top.

    Hi Naimesh,

    Is there any way that the grandtotal line could be hidden while displaying the subtotals ?

    Hi Naimesh,
    I need to hide grandtotal line which is shown with subtotals.

    how can i achieve this?

    Hi Naimesh,
    I want to schedule this report in background and still get the changes i did for my subtotals. Can you help out to code this ?

    Thanks.

    Hi Naimesh,
    Is there a way for the classical ALV grid report ("Classical ALV: Change Subtotal – II for Print") to schedule in background and still have the subtotal changes in there ? can you help me code.

    Thanks

  • Hello,

    I will do some research to make it work and post it solution, if I come across any.

    Hello Naimesh,
    Thanks for replying. I have a requirement where i have to provide 7 subtotals with % which i have been successful using this code. But when the program was schedule it was a big boo-boo. It would be of great help if you can help me solve this.

    Thanks.

    This is done your blog was very helpful to resolve this issue.

    Excellent series!

    Is it possible to aggregate purely on the number of rows grouped together? I’ve found so far the only way I could do this is to add a column with ’1′ and aggregate that.
