Cloud Compatibility

abap2xlsx is designed to work on SAP BTP ABAP Environment, S/4HANA Public Cloud, and all classic on-premise ABAP stacks. This guide explains which parts of the library require classic ABAP and which are cloud-safe.

The not_cloud Package

Classes that depend on classic ABAP APIs are isolated in the src/not_cloud/ package. Do not install this package on cloud systems.

not_cloud Class Inventory

Class	Depends on	Alternative
zcl_excel_converter	DDIF_FIELDINFO_GET, DESCRIBE TABLE LINES	bind_table + zcl_excel_worksheet
zcl_excel_converter_alv	LVC_* ALV APIs	bind_table with manual field catalogue
zcl_excel_converter_alv_grid	CL_GUI_ALV_GRID	CL_SALV_TABLE + zcl_excel_converter_salv_table
zcl_excel_converter_salv_table	CL_SALV_TABLE model APIs	Cloud ALV (cl_grid_display_salv, future)
zcl_excel_converter_salv_model	CL_SALV_*	Same as above
zcl_excel_converter_result_wd	CL_WD_RUNTIME_SERVICES	OData/REST file download
zcl_excel_ole	CL_GUI_FRONTEND_SERVICES, OLE/COM	Server-side writer + HTTP download
zexcel_template_get_types	DESCRIBE TABLE COMPONENTS	Manual structure inspection

See ALV Converter and OLE for full usage documentation on all not_cloud classes.

What Changed for Cloud Compatibility

The following statements were removed from the main src/ package classes and replaced with cloud-compatible equivalents:

Removed statement	Replacement
DESCRIBE TABLE lt_data LINES lv_count	lv_count = lines( lt_data )
DATA: lt_strtab TYPE STRTABLE	DATA: lt_strtab TYPE string_table
DATA: lt_sstrtab TYPE SSTRTABLE	DATA: lt_sstrtab TYPE string_table
DATA: lv_text TYPE SCRTEXT_M	DATA: lv_text TYPE string
DATA: lv_lang TYPE LANG	DATA: lv_lang TYPE sy-langu
DATA: lv_name TYPE SEOCLSNAME	DATA: lv_name TYPE string

The class zcl_excel_obsolete_func_wrap wraps function modules that are not available on cloud (GUI_DOWNLOAD, GUI_UPLOAD, POPUP_TO_CONFIRM, SAPGUI_PROGRESS_INDICATOR). The cloud-compatible replacements are cl_gui_frontend_services (on classic ABAP) or HTTP download (on BTP).

Cloud Installation

abapGit

Install only the main src/ package via abapGit. In the .abapgit.xml:

<asx:values>
  <DATA>
    <PACKAGE>ZABAP2XLSX</PACKAGE>
    <!-- Do NOT add ZABAP2XLSX_NOT_CLOUD for cloud systems -->
  </DATA>
</asx:values>

Or when cloning via abapGit online, choose only the ZABAP2XLSX top-level package and deselect ZABAP2XLSX_NOT_CLOUD (or the equivalent sub-package name in your system).

SAPlink / Manual Transport

Import only objects from src/ — do not import anything under src/not_cloud/.

Runtime Checks

A useful pattern before calling any not_cloud class is to check whether the class exists:

IF cl_abap_classdescr=>describe_by_name( 'ZCL_EXCEL_CONVERTER' ) IS INITIAL.
  " Running on cloud — use bind_table instead
  lo_worksheet->bind_table( ip_table = lt_data ).
ELSE.
  " Running on classic — use converter
  DATA(lo_conv) = NEW zcl_excel_converter( ).
  DATA(lo_result) = lo_conv->convert( it_data = lt_data  it_fcat = lt_fcat ).
ENDIF.
