A list displayed by the ALV Grid Control shows three different texts for a column:

  • The column header

  • The popup column selection (for example, in the current layout)

  • A tool tip for the column header.

For fields with Data Dictionary reference, the system automatically adopts the field labels of the corresponding data element. The texts for the short, medium and long field labels as well as for the header are copied into the fields SCRTEXT_S, SCRTEXT_M, SCRTEXT_L and REPTEXT of the field catalog.

There are several possibilities how the ALV Grid Control assigns text to a column:

  • If no other text is specified, the text copied from the Data Dictionary is used. The ALV Grid Control choses the long field label (SCRTEXT_L) as the tool tip and the text in the popup column selection. The column header is dynamically adjusted to the column width even if the user changes the column width. The ALV Grid Control always uses the longest DDIC text that still fits into the column.

  • If fields COLDDICTXT, SELDDICTXT or TIPDDICTXT of the field catalog are not empty, the relevant field determines the field label that is to be displayed as the column header, the popup column selection or the column header tool tip. The value range of these fields is as follows: SPACE, 'L', 'M', 'S' and 'R'.

  • You can use the fields COLTEXT, SELTEXT and TOOLTIP of the field catalog to define your own texts for the column. If field labels have been copied from the Data Dictionary, these are ignored. You must fill these fields if you want to display fields without reference to the Data Dictionary.
