ABAP code is used with SAP query tool to enhance the query output.
You can write down the code under the Extras tab for the Infoset in the SQ02 Tcode.
You will find various coding events which are similar to classical ABAP report.
The code written in this code area is transmitted to the auto generated query report. You can write down your code in various coding section as per the use of them.
- DATA Section :
Global Data Declaration will go under this Event.
- INITIALIZATION Section :
As the name suggests it is used to initialize the variable with initial values.
- AT SELECTION-SCREEN OUTPUT :
This event is triggered before the display of selection screen.
- START-OF-SELECTION :
This event is triggered before starting any database accesses. Usually Data fetching logic goes under it.
- RECORD Processing :
Corresponds to the GET coding with Info-sets without a logical database. As there is no hierarchical view of the data, all the join tables are addressed.
- END-OF-SELECTION :
The END-OF-SELECTION code consists of two parts (Before list output and After list output). The first part is processed before the list is output and the second part afterwards. It is the right section to do aggregated calculations and actions that can only be done when data from all the selected records has been extracted.
However, there is a problem when queries use code in the END-OF-SELECTION section in combination with the Sap List Viewer format. In short, the code is never reached.
- Free Coding :
The code under this event is executed after all the events are triggered.
Logic to put extra field in the query output:
Let you want a date field to be fetch from a ‘B’ table and has to be added to your query output.
Define a Structure in DATA Event:
data: begin of ty_date occurs 0,
date like B-date,
end of ty_date.
The logic to fetch the values for this field will go under the record processing event.
In Record Processing Event write down the following code:
CLEAR ty_date.
CLEAR v_date.
Select date from B into table ty_date. “You can mention your condition also with where clause
Sort Table ty_date BY date DESCENDING.
Read Table ty_date INDEX 1.
v_date = ty_date-date.
Generate the Infoset.
Changes to the query:
1.Run SQ01 in another session.
2. Open your Query in change mode and select the field group in which has the added extra field.
3.Select extra field.
4 Click on basic list to select that field in your O/p list.
5.Click on Test button, and see if you are getting desired result.
Performing Operations on the final output table data:
You’ll find table %G00 with final data to be displayed.
Enter the following ABAP code under Data Section:
data: str type string.
field-symbols: <G00> type table.
field-symbols: <G00_WA> type any.
Enter the below ABAP code under END-OF-SELECTION(after list) Event:
str = ‘%g00[]’.
ASSIGN (str) TO <G00>.
loop at <G00> assigning <G00_WA>.
…do whatever you like here….
endloop.
You can put your own logic inside the loop to perform. .
Hi Amit,
I want to add the condition against the fields in the loop. How to do that ?
Loop at <G00> assigning <G00)WA>
Endloop.
You can write down the code under the END-OF-SELECTION(after list event) by Looping on the table G00.
Hi Amit,
Thanks for your reply. I got the answer.
regards,
Sam…
very useful document. I used this document for many times.. instead of keep remembering things, I remember this kind of document , so I can use it, whenever its required.
Hi Amit, thanks for your explanation. I´m functional consultant and I´m used to create infoset/queries. I have an issue now that I need to summarize (collect) the result of the infoset I created. How can I do it ? How can I refer to the internal table the infoset creates during runtime and summarize it before is listed in the report result ? Best Regards and thanks if you have time to save me
Hello Frederick,
The result set for the infoset queries is in G00 Internal table. You can consult with the abaper to make changes to the data in this final table. For runtime modification to the final output data of the query we generally write down the code.
Please let me know if you need more information on same.
Is it possible to change, update and delete database table entries using ABAP coding in SAP Query?
Hello Francis,
You can make all the mentioned operations on the result set of the infoset queries which we received in G00 Internal table.
Hi Amit, In the Query there’s a field with label SAP List Viewer where user can put the layout for the output. I created a parameter in the infoset called ‘layout’ and basically hidden SAP List Viewer now I want to transfer the value from my own parameter (i.e. layout) to the value of the SAP List Viewer which in the code is %ALVL…can this be done. Thank you
