Field Validation for ME21N

[Former Member]

Hi All,

I would like to ask which user-exit can be used for data checking for the inputs when creating a purchase order using ME21N. I would like to prompt an error message in case the user has enter a wrong value for the field. Thanks.

Thanks.

Hi,

Go to smod go to f4 help put ME as development class you would get the list of exit that would be called in ME21N. check the same.

You can also use ME_PO_BADI_CUST. BADI.

You can use Exit MM06E005 exit, fm EXIT_SAPMM06E_012 like below:

CASE OK_CODE.
 
  WHEN 'MECHECKDOC' or 'MESAVE'. 
then put your checks

Hi,

As said above, you can do your checks in the below exit: EXIT_SAPMM06E_012

But you need to take care of Create/Change/Display transactions as if you are aware that each of the transactions have the Toggle button where in you can directly change values in ME23N also. Hence in addition to SY-TCODE check, you need to check the value in I_TRTYP parameter of the exit.

I_TRTYP = A/V/H (create/change/display). Please check exact values in debugging.

Hope this helps
