Introduction
There could be multiple scenarios where an excel upload and download using ABAP Report Program or a Odata service with different sheets or tabs in a Excel needs to developed as shown in the below screenshot.
Excel Upload with multiple tabs :
There has been multiple instances where most of the developers tend to use the function module ALSM_EXCEL_TO_INTERNAL_TABLE,TEXT_CONVERT_XLS_TO_SAP .This will work fine when we test the program or Odata from SAP GUI .
Disadvantages of using the ALSM_EXCEL_TO_INTERNAL_TABLE,TEXT_CONVERT_XLS_TO_SAP FM :
Proposed Solution :
The below code can be leveraged to upload and read the excel with multiple excel tabs or worksheets .
Once the Data has been read into two different internal tables use the below methods to the read the data and process it .
In the below example the dynamic internal tables are converted into header and items strucutres.
Similarly dynamic structure names can also be provided for the same.
Additional check for the Date format and other data structure can be performed in the loop as shown above.
Generate and Download Excel with multiple tabs or sheets from WEBGUI or Fiori Lauch pad :
There are classes like CL_SALV_EXPORT_TOOL_ATS_XLS which could be used to achieve the above functionality .However we could not use this since it will not work creating multiple tabs or sheets.
Suggested Solution :
The only solution which could solve this problem :
Below is the sample code using the abapGit classes to achieve the same :
Additionally we can also add hyperlinks and also colors to the excel sheets using the abapGit.
Please provide your valuable feedback .

Excel Upload with multiple tabs :

Disadvantages of using the ALSM_EXCEL_TO_INTERNAL_TABLE,TEXT_CONVERT_XLS_TO_SAP FM :
- This function module which uses OLE object for Office Integration solution internally will produce a dump and is not supported when used in the SAP ABAP Program Odata when called from Fiori launch pad since this is web based HTTP application with WEBGUI and no OLE is supported similar to the SAP GUI .
Proposed Solution :
The below code can be leveraged to upload and read the excel with multiple excel tabs or worksheets .
- Use the Class CL_FDT_XL_SPREADSHEET in order to over come the above issue by instantiating and passing the XSTRING data in the constructor
- In Odata use the CREATE_STREAM method to write the below code
- IF_FDT_DOC_SPREADSHEET~GET_WORKSHEET_NAMES returns both the tabs as internal tables .
- Use the method IF_FDT_DOC_SPREADSHEET~GET_ITAB_FROM_WORKSHEET to get the corresponding tab into internal table by passing the sheet or tab number.

Generate and Download Excel with multiple tabs or sheets from WEBGUI or Fiori Lauch pad :
There are classes like CL_SALV_EXPORT_TOOL_ATS_XLS which could be used to achieve the above functionality .However we could not use this since it will not work creating multiple tabs or sheets.
Suggested Solution :
The only solution which could solve this problem :
- Install the abapGit using the below link :abapGit documentation - Installation
- Perform the SSL setup using the STRUST transaction
- Import the custom code required for the excel generation using the below link: https://github.com/sapmentors/abap2xlsx
- This custom code should be captured in a transport and the same should be transported along with your report or Odata.
Below is the sample code using the abapGit classes to achieve the same :
