Editable ALV Report

We can edit an ALV report on the screen and then we can download it as per requirement. Here we are discussing about two ways to edit an ALV report.

1.       The first way is to use the field catalog manually and there we can active the EDIT field of field catalog. In this way we can manually select the fields which need to be edited. The statement is as follows.

    lv_col            = 1 + lv_col.
    wa_fcat-col_pos   = lv_col.
    wa_fcat-fieldname = 'CURRCODE'.
    wa_fcat-tabname   = 'IT_SCARR'.
    wa_fcat-edit      = 'X'.               "Editable field
    wa_fcat-seltext_l = 'Local currency of airline'.
    APPEND wa_fcat TO it_fcat.
    CLEAR wa_fcat.

2.       Second way is to active the EDIT field of layout. This way gets the whole report editable. We can edit each and every field. Statement is as follows.

  wa_layout-colwidth_optimize = 'X'.
  wa_layout-edit = 'X'. "This activation will let all fields editable

In the following example we have demonstrated the first approach where we are manually using the editable fields by field catalog.

The output is as follows.

The basic output.

Now we can edit those two fields as per requirement.

Now we are using the second approach where we need to activate the EDIT field of layout. With this approach the whole report will be editable.

Below is the output where we can see every field is available to edit.

We have edited one as per requirement.
