## SAP ABAP ALV: LVC_FIELDCATALOG_MERGE how to use?

Understanding Field Catalog in ALV (ABAP List Viewer) In ABAP, the field catalog is a key element when working with ALV (ABAP List Viewer) to define how the data from internal tables is displayed. It provides control over various properties of the fields displayed in the ALV, such as column headers, alignment, visibility, editability, etc. Key Concepts: Field Catalog: This is a table (usually of type lvc_t_fcat for modern ALV grid or slis_t_fieldcat_alv for old ALV grid) that contains metadata about each field of the internal table displayed in the ALV. It defines how each column should appear (e.g., column headers, field alignment, output length). Creating a Field Catalog: You can manually define a field catalog or use a function module like LVC_FIELDCATALOG_MERGE to automatically create one based on a data dictionary structure (DDIC). After generating the catalog, you can modify it to adjust field properties.

## Timestamp display in ALV

The provided text contains information and code related to working with timestamps and formatting them for display in an ALV (ABAP List Viewer) table. Here's a breakdown of the key points: Timestamp Format Transformation: The text begins with a description of a timestamp represented as '20,201,004,223,429' and the desire to format it as '2020-10-04 22:34'. This indicates a need to transform the timestamp from one format to another for better presentation. ABAP Code: The code section titled "FORM modify_fieldcat" shows a piece of ABAP code that is likely part of an ABAP program. It appears to be working with field catalog entries for an ALV display. In this code, a specific field with the name 'TIMESTAMP' is being modified. The modifications include setting the field as non-editable ('-edit = ' ''), indicating it's a column option ('-col_opt = 'X''), and specifying an edit mask for formatting ('-edit_mask = '____-- :''). Timestamp Conversion: The text also provides information about converting date and time into a timestamp and vice versa. It mentions that you can convert date and time into a timestamp using the 'CONVERT DATE' syntax and split a timestamp into date and time using the 'CONVERT TIME STAMP' syntax. This is useful for scenarios where you need to work with both date/time and timestamps. In summary, the text is primarily focused on formatting timestamps for display in an ALV table, and it includes relevant ABAP code for modifying field catalog entries to achieve the desired formatting. Additionally, it provides information about how to convert between date/time and timestamps when needed in ABAP programming.

Mandżuśri, figlarny uczeń Siddharthy, poddał próbę mnicha medytującego nad brzydotą, przemieniając się w piękną nimfę. Mnich, choć długo opierał się pokusie, w końcu uległ. Gdy odkrył, że nimfa była iluzją, Mandżuśri wyjaśnił, że zarówno piękno, jak i brzydota to jedynie koncepcje, które zniewalają umysł.
