Overwrite Standard Validation message to Custom message

[Former Member]

Hello Gurus,

I searched and have gone through lot of resources but did not find solution and came up with this question.

I have a scenario where I can not make action(Save) as validation independent. So, I tried using IF_WD_MESSAGE_MANAGER methods in WDDOBEFOREACTION as below.

1) Used HAS_VALIDATION_ERRORS If true got all the messages using method GET_MESSAGES.

2) Loop through messages of perticular attribute and deleted message based on MSG_ID using REMOVE_MESSAGE.

3) And tried to set custom error message using REPORT_ATTRIBUTE_ERROR_MESSAGE.

But to my suprise IF_WD_MESSAGE_MANAGER->GET_MESSAGES is not returning any messages even though there exists a validation erro, though HAS_VALIDATION_ERRORS returning TRUE.

Cant we make use of GET_MESSAGES in WDDOBEFOREACTION or anything wrong in my logic.

Any inputs would be appreciated!

Thanks a ton in advance!

Regards,

Pavan.

Hi Pavan,

if i am not wrong, you want to hide standard validation messages specific to data types and then put your own custom messages instead. for this

you have to use if_wd_validation interface and its methods to suppress those validation errors and then use report_attribute_message to put your custom messages (or) at first hand avoid those data type errors by using character or string data type

Hope this helps.

Thanks for the response!!

@ Srinivas: Sorry, I missed one more step wherein I use message object(MSG_OBJECT) of messages returned by GET_MESSAGES to get the specific message using GET_TEXT.

So, to rephrase I will only overwrite specific error message with my custom message.

@ Kranthi : Before posting the question I found the forum suggestion you mentioned but did not find a way to get reference to it.

Please tell me if you know how to get reference of IF_WD_VALIDATION in WDDOBEFOREVALIDATION to use it.

Pavan,

Then did you place the get_Text method in correct place? because i think, once the validation of one field is over, it goes to next , at that time I hope new msg will overwrite the previous one.

Hello Srinivas,

I could take care of the placing of GET_TEXT, but the actual problem to which I am seeking solution is GET_MESSAGES is not returning any messages even though validation errors exist on screen.

Please provide me inputs in this direction.

Thanks in Advance!!

Hi pavan,

you can get the reference for if_wd_validation using below code

data:lo_msg_mgr type ref to if_wd_message_manager,

lo_val type ref to if_wd_validation.

lo_val ?= lo_msg_mgr.

i hope you will have message manager reference variable anyways.

hi pavan,

let me rephrase your requirement,

You want to avoid all standard error messages and conveying the same with single custom message ?
