ALV report with variable rows

[Former Member]

Hi All,

I have a requirement to display an alv report for below scenario.

Header1

Details

Footer

---

Header2

Details

Footer.

--

The above no. of blocks may vary based on report selection.

I need to know how can we build multiple field catalogs and pass field catalog and data from my internal table to build the above scenario.

Note: My Internal table is having data in below format and I am using the same to generate output txt file. I need to show the similar details in alv.

Internal Table Data:

Header1

Details Record 1

Details Record 2

Details Record 3

Footer ( remains constant )

Header2

Details Record 1

Details Record 2

Details Record 3

Footer ( remains constant )

and so on..

Thankyou for all your help.

You can do this by using block ALV.

DATA :  IT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV, 
        T_LAYOUT TYPE SLIS_LAYOUT_ALV,
        T_EVENT1 TYPE SLIS_T_EVENT,
        T_EVENT2 TYPE SLIS_T_EVENT.

DATA :  B1_IT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,
        B1_WA_FIELDCAT TYPE SLIS_FIELDCAT_ALV.

DATA :  B2_IT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,
        B2_WA_FIELDCAT TYPE SLIS_FIELDCAT_ALV.

Thankyou Suresh!

Do you mean B1_IT_FIELDCAT is for header record and B2_IT_FIELDCAT is for detail record?

My actual data is somewhat like below:

1st row is header row and last row is footer. Middle rows are details and they can vary.

This is one block and I can have multiple such blocks of data in my output.

Could you please provide some more details to achieve the desired output?

Appreciate all your help!

Thankyou Suresh!

I was able to achieve the required functionality using the ALV Blocked LIST.

Created 3 Field Catalogs ( for header, detail and footer ) with 3 internal tables and Appended appropriate data using FM 'REUSE_ALV_BLOCK_LIST_APPEND'. And Finally using FM 'REUSE_ALV_BLOCK_LIST_DISPLAY' for displaying.

Thanks again!

ALV block, or tab strip, or splitter, etc. What did you search, what did you find, what did you try, what do you think?

[RaymondGiuseppi]

• Among the main classes of ALV, which ones have you already considered?
• Is usage of ALV mandatory?

Hint: Look at some samples such as ALV Object Model – Hierarchical Sequential List – The Basics which use CL_SALV_HIERSEQ_TABLE.

Hi Raymond,

Thankyou for sharing the valuable inputs. This may be helpful at some point.

However for now, my requirement is bit different.

I have the data in the single internal table of type string ( which i am using to generate the output file )

The output is 3 variable rows of data:

1. Type 1 records are Header ( This is not the header of the report ). For example: These record provide the date range and company details etc.

2.Type 2 records are Details. These records have punch in , punch out details for the employees.

3.Type 3 record. This is a constant footer.

I have the entire data in a single table.

These 3 types of records have their own field names ( for example: Type 1 will have, company name, rep id etc. Type 2 will have punch in , punch out etc,)

The only thing that i am looking for is how can I have generate ALV output for above mentioned 3 types of data records and pass their field descriptions accordingly.

The Binding method using Main Class - CL_SALV_HIERSEQ_TABLE should work for 2 variable data records as per example shared by you, however in my case I have 3 types of data records and don't have a common column for 3rd Type ( footer ) to bind. Also not sure if the binding works for more than 2 data records.

I am new to ALV. Any Inputs are highly appreciated!

Thankyou!

Could you then elaborate on: 'Footer ( remains constant )' - There is no data in this record, it seems only to exist to record the end of a document, why would you display it?

• If this record is not actually required you can use CL_SALV_HIERSEQ_TABLE which handles two level (e.g.header, item)
• If you want to display this 3rd record, it won't be as easy with ALV (personally I would then go on a html display - xml viewer like)

Hi Raymond,

The client requirement is to display the 3 footer record.

Could you please share some details for alternate method that you have proposed.(html display )

Thankyou!

[RaymondGiuseppi]

Look for some SAP samples at transaction DWDM (Examples and demos by SAP) for sample of gui tree.or a tool such as Abap2Xlxsx

But IMHO if you want a not too complicated ALV report you should use a single format for header/footer an another format for detail so you can use the ALV block/hierarchy tool (and use a total row to simulate the footer display.)
