Debugging issue in ME21N

[Former Member]

Dear All,

I am creating a PO.

I kept vendor field blank purposefully and hit enter.

Now at this stage I see an error message 'Enter a Vendor'.

I need to verify the same message in debugging mode to basically understand how the system performs the check before throwing this error message.

I am looking forward to know the field name, table it checks for making validation of entered vendor, the programing condition etc...,in debug mode.

Can any one please help with steps to follow?

I know that /h will start debug mode. but what are the next steps to spot the exact location where the above message is triggered?

Thanks & Regards,

Shetty

Hi,

You have it in LMEPOF00 in this coding:

IF ekko-lifnr EQ space.
  IF ekko-bsakz NE bsakz-tran.
    MESSAGE e049.
  ELSE.
    EXIT.
  ENDIF.
ENDIF.

mmpur_metafield mmmfd_vendor.

IF lfa1-lifnr EQ space.
  mmpur_metafield mmmfd_vendor.
  MESSAGE e101 WITH ekko-lifnr.
ELSEIF lfm1-lifnr EQ space.
ELSEIF lfm1-lifnr EQ space AND ekko-bsakz NE bsakz-tran.  "594704
  mmpur_metafield_add mmmfd_purch_org.
  MESSAGE e027 WITH ekko-lifnr ekko-ekorg.
ENDIF.

You can find: set /H in box for tcodes, when debugging stars, in menu path, breakpoint / breakpoint at / sentence and write 'MESSAGE' and F8

I hope this helps you

Thanks. That was really helpful.

How can I know that I can find this error message in program LMEPOF00 ? Is there a way I can find out all the programs associated with ME21N?

Dear,

Double click on the message , take the class and number. Go to se91, enter it,select it and click the where used list button.

or during debugging you can make it stop at particular statements from the menu options..

Hi,

As I told you, set /H in box for tcodes, run ME21N with field of vendor empty, when debugging stars, in menu path, search breakpoint / breakpoint at / sentence and write 'MESSAGE' and press return, and run it with F8 after each breakpoint, it will stop in all messages that flow of algorithm finds
