Error when trying to get ALV data from standard program

EWim — Fri, 07 Feb 2025 09:55:02 GMT

Hello there,

I am new to SAP and ABAP and need some advice here. I am trying to write a z program that receives information out of the ALV grid of a standard program and writes these into an excel file. I tried the following code:

cl_salv_bs_runtime_info=>set( EXPORTING display = abap_false metadata = abap_false data = abap_true ). SUBMIT (p_report) USING SELECTION-SET p_var AND RETURN. TRY. cl_salv_bs_runtime_info=>get_data_ref( IMPORTING r_data = DATA(ls_data) ). ASSIGN ls_data->* TO <lt_data>. CATCH cx_root INTO DATA(e_txt). WRITE: / e_txt->get_text( ). ENDTRY.

Everytime I run it I get an Exception of the type "cx_sy_struct_attributes" that isn't declared in RAISING. I've tried to find the error with the debugger but I could not find much. I only know that the error occurs in the following code:

cl_salv_bs_runtime_info=>get_data_ref( IMPORTING r_data = DATA(ls_data) ).

Can someone help me find the error or has a different idea on how I get the AVL data from a standard program (in my case RTPM_TRL_SHOW_FLOWS) into an internal table?

Thanks in advance 🙂

EDIT:

I've looked at the issue again in the Debugger but I am not quite sure what to do with it.

I've figured out that there is a suffix for component 9 even tho it is not allowed:

This is what lt_comp and lt_components look like:

The issue appears when the following method is called:

I am honestly very lost on what's going on and how to solve it.

The error indicates some Inconsistent Structure Table?

Did you already

Define your extracted internal table as TYPE TRLY_FLOW_ALV (or TABLE OF TRLS_FLOW_ALV)
Use R_DATA_DESCR for some dynamic coding with RTTI
Debug to look at actual received data type
Try to use GET_DATA and not GET_DATA_REF

Could you provide definition of fields such as LS_DATA (TYPE REF TO DATA?)

When it happens, you can debug and find the location where it's raised. Add a break-point there, run again, and see the values of the components. Reason/my 2 cents: one of the components has a "non-strict" name (i.e. a special character in the name like a dash), and it's not supported.

Are there any enhancements to the TRLS_FLOW_ALV structure or report logic in your system?
Call the report directly and view the ALV Consistency Check for 'exotic' fields in internal table and/or field catalog.

@Sandra_Rossi I have upated my post with screenshots from the Debugger. I don't think the issue is the name of a component but the suffix of it. Can you maybe help?

Thank you for your help @RaymondGiuseppi !

I have tried to define my extracted internal table as TYPE TRLY_FLOW_ALV and LS_DATA as TYPE REF TO DATA. Sadly it did not make a difference. I have updated my post with screenshots of the results from the debugger.

I have not tried GET_DATA instead of GET_DATA_REF and I did not use R_DATA_DESCR yet. I will look into it and come back with updates.

EDIT: There are also no enhancements made to TRLS_FLOW_ALV and the ALV Consistency Check also shows nothing.

I've now tried using R_DATA_DESCR and also tried using GET_DATA instead of GET_DATA_REF. Sadly I still get the same error.

You're correct, and the reason of the failure is that cl_salv_bs_runtime_info is using the RTTS creation strict mode, and included structure with suffix is not supported in strict mode. The only way (*) to make it work is to enhance/modify cl_salv_bs_runtime_info to make it run RTTS in strict mode.

(*) EDIT: as Raymond found out, there is a fix by SAP concerning RTPM_TRL_SHOW_FLOWS, they changed the DDIC structure TRLS_SUBPOSITION_I so CL_SALV_BS_RUNTIME_INFO can now be used. No need to enhance/modify cl_salv_bs_runtime_info. 3288856 - CL_SALV_BS_RUNTIME_INFO stops with runtime error UNCAUGHT_EXCEPTION and exception CX_SY_STRUCT_ATTRIBUTES in class CL_ABAP_STRUCTDESCR - SAP for Me

@Sandra_Rossi as someone being new to SAP/ABAP how would I make sure that cl_salv_bs_runtime_info is running in the correct mode if i decided to modiy/enhance it. Also is there maybe a different way to get the output data from another report (in my case RTPM_TRL_SHOW_FLOWS) without using cl_salv_bs_runtime_info that avoids this issue? Thank you so much for your help! You definitely cleared some things up for me! 🙂

Good news - 3288856 - CL_SALV_BS_RUNTIME_INFO stops with runtime error UNCAUGHT_EXCEPTION and exception CX_SY_STRUCT_ATTRIBUTES in class CL_ABAP_STRUCTDESCR

@RaymondGiuseppi I don't know how I missed that... Thank you so much for your help!

My systems had been updated too recently for me to see the anomaly. I had to remove my advanced search filters for notes
