SAP Web UI Custom field value not getting set .

[naval_bhatt4]

Hi All,

We have a custom field which is created as a numerical field .

When I am trying to enter the field with a numerical value its not getting updated

ie; when I press enter after entering value in UI it disappears .

But when I enter chars it accepts the value .

Code snippet for GET and SET methods are .

Hi Naval,

How did you solve this by implementing _M_ and _P_ methods ?.

Hi Raj ,

I think it was M method ..... P is for the field type it doesnt control the input values validation..

[naveenkolathuru · Accepted solution]

Hi Naval,

I'm facing the same issue. Would please provide the code in M method.

AET wont support to add field to BTREFOBJ ,so I added date field in BOL Structure and added to config . I can choose the value of date , as soon as i hit enter value disapper. In set method dref is not bound. Suggest me how to fix the issue.

Thanks,

Naveen.

Hi Naveen ,

I suggest you to first test the BOL , in BOL model browser .

you should check if the field is available in the structure, after that you can fill the dref with the BOL entity from iterater

would have been far better if you would explain how rather than just saying Done.

hi,

I am facing similar problem,  text or numeric entries not getting set,  it is an model custom attribute but not getting set,  How did you solve it..

thanks

You need to set the appropriate meta data value for the field type . its either the _M_ or the _P_ method. Implement them as well.

Reward points if problem is fixed.

Cheers
