AMDP method call error

Sadullah75 — Sun, 24 Dec 2023 19:16:00 GMT

Hey experts,

I checked other answers and can't resolve my issue.

I'm trying this very simple tutorial about AMDP implementation. I'm stuck at method_call_error, getting a short dump.

I created a global class and call its method in an ABAP program. Also I have a transparent table and table type. I tried to fix with adding and removing MANDT. When I debug,

CASE SY-SUBRC.
    WHEN 0.
    WHEN 1.
*     system_error
      MESSAGE ID 'CNDP' TYPE 'X' NUMBER 007 RAISING CNTL_SYSTEM_ERROR.
    WHEN 2.
*     method_call_error
      MESSAGE ID 'CNDP' TYPE 'X' NUMBER 006 RAISING CNTL_ERROR.
    WHEN 3.
*     property_set_error
      MESSAGE ID 'CNDP' TYPE 'X' NUMBER 006 RAISING CNTL_ERROR.
    WHEN 4.
*     property_get_error
      MESSAGE ID 'CNDP' TYPE 'X' NUMBER 006 RAISING CNTL_ERROR.
    WHEN 8.
*     maximal number of modi reached
      MESSAGE ID 'CNDP' TYPE 'X' NUMBER 011 RAISING CNTL_SYSTEM_ERROR.
    WHEN OTHERS.
      RAISE CNTL_ERROR.
  ENDCASE.

I'm getting the 2nd "method_call_error".

ENDCLASS.

Actually am expecting, if my system doesn't support AMDP, I'll get the message which is in IF scope.

I saw a comment "After the first succesful call you shouldn't reach that method in the debugger any more.", but I don't have a conclusion from this info.

I'm running SAP Developer Edition 7.52 NW on a VM. Eclipse and ADT installed and I believe they're working as well.

What should I do? Thanks in advance. Happy New Christmas. Frohe Weihnachten. 😃 I'm sorry for annoying you during these days.

Please attach the short dump. Also debug/catch the error to see the exception details.

You are posting code concerning CNDP errors, it means a SAP GUI error, so it's not related to AMDP.

If it's ABAP Trial 7.52 SP01/04 Developer Edition, the database is Sybase, not HANA, so it's normal.

So It means I can't practice AMDP with developer edition, right?

My SAP GUI is for Java because I'm using Ubuntu as OS.

SAP teach how not to learn something. I don't have a real system currently because of not working.

OK, this case is closed.

I can't practice AMDP with SAP Developer Edition 7.52 SP04 because the database is SYBASE not HANA.

With HANA database: ABAP Platform Trial 1909 Available Now | SAP Blogs

(32 GB RAM / 512 GB SSD highly recommended)

16 GB RAM 256 SSD for now, insufficient resources =D

I'll try to get a real sys which is affordable. Thanks for your help, you're great.
