Regarding ALV Grid Control using OOPs concepts

Former Member — Sat, 21 Jul 2007 07:13:49 GMT

Hi ABAP Gurus,

Acutally i dnt have any knowledge on OOPs concepts, i have an object i.e. ALV Grid Control using OOPs concepts..

hope tht sumone will help to get through

here is the requirement, if at all anyone had already done the related , pls send the stuff needed or else any suggestions

OBJECT:

Technical specification deals with the Table Maintenance handled for the Z tables through ALV GRID control in a Module Pool Program.

Screen processing logic

Based on the selection criteria filled in the first screen of the transactions, rows are selected from the corresponding Z tables and displayed via an ALV grid control in Screen 1002.

Validations

Screen 1000:

Check the database entries for the Selection criteria. If the database entries do not match then display error message in the Status Bar for the respective entry.

Screen 1001:

Check the database entries for the Selection criteria. If the database entries do not match then display error message in the Status Bar for the respective entry.

Screen 1002:

When the Save button is pressed and an empty row(s) is/are saved, then delete the empty rows that have been inserted.

When the Save button is clicked, the field entries are checked with the Database entries and if any discrepancy is met, an Error message is displayed in the Status bar stating, “Check the Field Entries”.

After the entries are saved successfully to the database table a Success message is displayed in the Status bar, “Changes were saved”.

When the Change/Delete button is pressed without selecting any row then display the error message stating, “Select a row to perform the operation”.

When the delete button is clicked, a pop up is shown to confirm delete and pressing the delete button again deletes the row/rows which has the lock icon.

When the user clicks the Display button, a pop is shown to confirm for save.

Have a look at below link. Its a PDF document Which will give you information abt OO ALV.

http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCSRVALV/BCSRVALV.pdf

Also have a look at below link.

http://help.sap.com/saphelp_nw2004s/helpdata/en/5e/88d440e14f8431e10000000a1550b0/frameset.htm

Check the following standard programs also.

*& Include Z_TABLE_DISPLAY

VERSION 2

Code from François Henrotte (EPONA Solutions)
http://www.eponasolutions.com
Belgium
Please keep reference !

*********************************************************************

HOW TO

Display an ALV grid :
CALL METHOD lcl_table_display=>display_grid( 'tabname' ).

Display a hierarchical list with header and detail :
CALL METHOD lcl_table_display=>display_hier( in_header = 'table1'
in_detail = 'table2' ).

Display a block list with two tables :
CALL METHOD lcl_table_display=>set_block_mode( 'X' ).
CALL METHOD lcl_table_display=>display_grid( 'table1' ).
CALL METHOD lcl_table_display=>display_grid( 'table2' ).
CALL METHOD lcl_table_display=>end_block_list( ).

You never have to deal with field catalog of tables !!

What if field catalog has to be changed anyway ?

ob_table = lcl_table_display=>create_table( 'tabname' ).
CALL METHOD ob_table->set_alv_fieldtext( in_field = field
in_ftext = 'text' ).
CALL METHOD lcl_table_display=>display_grid( 'tabname' ).

Re: Regarding ALV Grid Control using OOPs concepts

Former Member — Tue, 24 Jul 2007 14:27:32 GMT

i wld like to thank you first for sharing.

but in my alv grid , i need these functionalities, let me knw how can i do get them...., pls can u provide the code if at all u can...

If Insert Row button of Screen 1000/1001 was clicked:

If the Insert Row button was clicked the ALV grid is displayed to the user but with no content. But the ALV grid is constructed to have the same structure of the corresponding Z table following the respective transaction as mentioned above.

If Maintain Entries button of Screen 1000/1001 was clicked:

If the Maintain Entries Button was clicked, then the ALV grid is displayed with the database entries based on the Selection Criteria for the Z tables. These are also loaded into the internal table IT_TAB_ROWS.

There are various options provided in the Screen 1002 to facilitate the user to maintain the Z tables.

They are:

Insert row:

Inserts a row in the ALV grid. The row index of the row that has been inserted is loaded into the internal table IT_TAB_ROW_INDEX. When a row is inserted, all the entries are blank except the Costing Version. This entry is internally filled by the program using the value Z_GL_ALLOC_PLAN_VERSN from the TVARVC table and this field is set as disabled in the ALV grid.

Select All:

Select All button when clicked selects all the rows that have been displayed in the ALV grid.

Deselect All:

Deselect All button when clicked deselects all the rows that have been selected previously.

Save:

1) When the save button is clicked the user is prompted with the confirmation to save the data.

2) If the user agrees to save the data then the rows then the changes are updated to the database. This can be identified by the rows that have been selected for change mode (on which the lock icon is present). The lock icons will be removed, the changes will be reflected in the database and the rows are displayed in the display mode. The internal table IT_TAB_ROW_INDEX is looped to fetch the row index and then the row details are fetched from the ALV grid. These row details are loaded into the internal table IT_TAB_ROWS. If the row already exists in the internal table then the row is modified, and the field CHANGED is marked as ‘X’. If the entry does not exist, then a new row is inserted into the internal table IT_TAB_ROWS and the INSERTED field is marked as ‘X’. Now the internal table IT_TAB_ROWS is looped to select the rows with CHANGED field as marked. These rows are inserted into the Z table, and the rows with INSERTED ‘X’ is selected and they are inserted into the Z table.

3) If the user rejects the save option then, discard the changes made, remove the lock icons and display the rows in display mode.

4) The rows which are newly inserted are also saved to the database after validating them with the database entries.

Change/Display:

Change:

1)When row/rows are selected and Change option is clicked then, locking is applied for the particular row/rows in the Z table.

2)If the locking succeeds, a lock icon appears near the row/rows and the Savings% fields of the row/rows are activated in change mode. The row indexes of the rows are stored in the internal table IT_TAB_ROW_INDEX.

3)If the locking fails for the row then, a message is displayed in the Status bar stating “Locking failed for the row(s) selected” and the row/ rows selected are in display mode only.

Display:

1)When row/rows are selected and the Display option is clicked then, the user is prompted for a Save of the data.

2)If the user, confirms the Save, then the changes are accepted, the lock icons are removed from the row/rows and the row/rows are activated in display mode with the updated data. Follow the same logic used in the Save button.

3)If the user rejects the Save, then the changes are discarded, the lock icons are removed and the row/rows are activated in display mode.

Delete:

When the row/rows selected needs to be deleted, then the Delete button is clicked.

When the delete button is clicked, user is given a pop up which says that locking has been applied to the row/rows and he/she needs to click the delete button again to delete the records. A lock icon appears near the row/rows for which locking was successful. These row/rows will be selected. The indexes of the row/rows are loaded into the internal table IT_TAB_ROW_INDEX. When the user clicks the delete button again, the rows for which the lock icon appeared will be deleted. This is done by loading the indexes of the row/rows into the internal table IT_TAB_ROW_INDEX. The internal table is looped and the row details are fetched from the ALV grid. For this row in the internal table IT_TAB_ROWS the DELETED field is marked as ‘X’. The records which has ‘X’ marked in DELETED field are selected and they are deleted from the Z table.

Sort:

Selecting the column and clicking the sort button will enable the data to be sorted based on the column.
