implementing user exit

Former Member — Tue, 19 Sep 2006 04:41:00 GMT

Hi Abappers,

I am trying to implement a customer defined validation in the user exit EXIT_SAPFP50M_002 in PA30 transaction. I want to display a particular error message, if the particular wage type is entered in the second screen(2010), but after displaying the error, the screen fields get greyed out. i want to enable the user to edit the fields after the error message has appeared. How should i do this? please suggest me a solution.

Regards

Naren.

Try using a information message.

Hi senthil,

The requirements is that the user is not supposed to save the entry if the entry is wrong,that is the reason for using error rather than status of info message.Can you please help me with this?

Hi,

In user-exit, the control doesn't come back to your screen when you throw a std error message. So, you have to call a pop-up screen and displayed the error message in the pop-up. That way, the control comes back to my screen.

Also try this,

INSTEAD OF

MESSAGE EXXX(XX).

USE.

MESSAGE SXXX(XX) DISPLAY LIKE 'E'.

FCODE = 'ENT1'.

Hi Narendiran,

In order to prevent the screen fields from being greyed out, use the chain...endchain construct. Inside the CHAIN..ENDCHAIN construct, mention the names of the fields as under to prevent the greying of the same.

CHAIN.

FIELD MARA-MATNR.

FIELD MARA-MATKL.

ENDCHAIN.

Hi,

i am implementing this exit inside a function module, is it possible to use chain endchain in this case?

Ok good,

Use this in your flow logic,

field <screen field name> module <module name> .

and place the code and error message with the module .

this will enable to field for entering new values.

process after input.

field <fieldname> module <module>.

module user_command_0100.

In an include of the main program.

************************************************************************

Module <module> INPUT

************************************************************************

module <module> input.

Insert the error message here!

endmodule.

Hi Senthil,

I am writing my validation code inside a Z include(ZXPADU02) inside the function module EXIT_SAPFP50M_002 which is an user exit provided by SAP in the transaction PA30(Maintain HR Data) , I tried using

SXXX(XX) display like 'E'.

fcode = 'ENT1'

intead of

but i dont understand what fcode corresponds to here?

Secondly i dont think i can implement

chain.

endchain.

structure here since, i am inside a function module.

Please suggest me a solution.
