Validate a Field in the Initial Screen of UI in FPM

[Venkat_Sesha]

  Hi Gurus,

I would like to validate this field in the Material Change initial Screen.

When the user Selects the particular Change Request Type. Then I need to Validate the Above entered plant against the Material Entered.

Where can I write the Code Logic for this validation from MARC table. Please help.

hi,

Catch the even 'FPM_LEAVE_INITIAL_SCREEN' in the feeder class and check condition as per your requirement.

Hi Ragavendra,

I am CRM Tech guy. I am bit fresh to FPM. Please shown me where can I find the feeder class and explain in detail what should I do there.

thanks

Hi,

Goto Form UIBB configuration and you can find the feeder class under Floorplan setting.

and catch the event in get_data method.

ok whats next.. after catching the event. I will validate plant against material there and throws an Abundant message. but still goes to next screen.

[former_member215610 · Accepted solution]

Have you appended error message into ET_MESSAGES?

[Venkat_Sesha · Accepted solution]

yes ofcourse. There is a Strucute like ucms_messge or something I dont remember and I appended with msgty, msgid, msg1, blah blah blah.. The abandoned message is thrown on the screen but when I click on EDIT again with same data it goes to next screen.

Hi

I Think it is raising LEAVE_INITIAL_SCREEN event try to check where this event is raising.

and based on your condition do not raise this event.

LEAVE_INITIAL_SCREEN-is use to leave initial screen.

code will be link this:

data: lo_fpm type ref to if_fpm

lo_fpm = cl_fpm_factory=>get_instance( )

lo_fpm->raise_event_by_id(IF_FPM_CONSTANTS=>GC_EVENT-LEAVE_INITIAL_SCREEN).

Hi Check what I have written and see what I got.

Please tell me how to fix this.

When I press Continue and the Error is Displayed on the Screen but It is going to the next screen where in my requirement is it should not go to next screen.

Though the error message it displayed on the screen it continues to the Next Screen which should not happen. Also Please find the below code what I have written in the GET_DATA Method.

Hi,

when you click on continue event LEAVE_INITIAL_SCREEN is raise so it is displaying message and navigating to next page.

Create a action validate and assign to continue button and write you logic in get_data method. if it is validated then raise event LEAVE_INITIAL_SCREEN other wise do nothing.

[Venkat_Sesha · Accepted solution]

I got it what you are trying to say. But I don't know how to do this part. Create a ACTION VALIDATE and Assign it to CONTINUE Button. How do I do this part.

Please explain in code or something that how to do this

[Venkat_Sesha · Accepted solution]

This is what I have written if there is a error message under GET_DATA Method

    READ TABLE ET_MESSAGES Into LS_USMD_MESSAGE With Key SEVERITY = 'E'.

    If Sy-Subrc = 0.

      lo_fpm = cl_fpm_factory=>get_instance( ).

      lo_fpm->raise_event_by_id( IF_FPM_CONSTANTS=>GC_EVENT-LEAVE_INITIAL_SCREEN ).

    Endif.

[former_member215610 · Accepted solution]

you can create a action using get_defination method by adding line item into et_action_defination.

and write the code to validate and append error message.

Read the et_message if severity = 'E' and if sy-subrc <> 0 then raise event LEAVE_INITIAL_SCREEN.

refer this code :

READ TABLE ET_MESSAGES Into LS_USMD_MESSAGEWith Key SEVERITY = 'E'.

    If Sy-Subrc <> 0.

      lo_fpm = cl_fpm_factory=>get_instance( ).

      lo_fpm->raise_event_by_id(IF_FPM_CONSTANTS=>GC_EVENT-LEAVE_INITIAL_SCREEN ).

    Endif.

Hello,

Most appropriate method of feeder class to terminate FPM event is PROCESS_EVENT. You must add message in ET_MESSAGES table and set EV_RESULT parameter in IF_FPM_CONSTANTS=>GC_EVENT_RESULT-FAILED for this.

Unfortunately this method does not contain UI data but for this purpose you can use FLUSH method of feeder class which is triggered before PROCESS_EVENT. Store value of IS_DATA parameter in your global variable in feeder class and use it for your checks in PROCESS_EVENT method.

Kind regards, Aliaksandr.

Hi AZ,

Thanks for the info. But still the same error remains.

In the GET Data I am checking some data validation and populating the error messages to a custom attribute in the class CL_MDG_BS_MAT_FEEDER_FORM_SET.

In the PROVESS_EVENT Method I am doing this.

oref type ref to CL_MDG_BS_MAT_FEEDER_FORM_SET.

and read oref->gt_message into WA with key severity = 'E'.

if sy-subrc = 0.

  Append lines of oref->gt_message to et_messages.

EV_RESULT = IF_FPM_CONSTANTS=>GC_EVENT_RESULT-FAILED

endif.

still the same problem remains. I get the error message when I click on continue and the screen moves to next screen with the error message on the top.

Hello,

GET_DATA method is triggered later then PROCESS_EVENT. Move your checks in PROCESS_EVENT method.

Kind regards, Aliaksandr.

[Venkat_Sesha · Accepted solution]

Hi AZ,

However after GET_DATA, process Event is also triggered. I wan to stop there, after GET_DATA.

bcox I need to capture the screen data that has been changed.

Though I wrote the same logic in Flush , when user presses continue, error messages are shown and the next screen is called.

Hello,

Could you post your implementations of FLUSH and PROCESS_EVENT methods?

Kind regards, Aliaksandr.

[Venkat_Sesha · Accepted solution]

Solved with some WD Post Implementation Method. Thanks everybody
