F4 Help for Characteristics

[Former Member]

Hi Experts,

I have created a characteristic 'Department' and when I assign the table 'T527O' in the Value tab it gives an error " Check table T527O has too many key fields".

In the error it says that "Check tables with more than one key field are not supported. However,

if you enter a function module for checking values, you can refer to any check table in your own coding."

I am able to see one radio button called "Function Module" when I click on Other Value Check on Value tab, but do not know how to use that.

Could anyone please guide me in this.

My requirement is:

1. create a characteristic called department.

2. link it to a class,

3. while creating a document in CV01N the f4 help should be available in department field.

Thanks & Regards

A function module is where you get an ABAP programmer to create a customer download linked to a table. He saves it as a function module and you add it there. When the person presses F4 it calls the function module and gives the user the drop down.

Thanks for the reply.

But if this was the case I would have not raised the question. I have created a function module as specified in the F1 help, but still the value is not coming.

Thanks & Regards

Hello Rajiv,

You must create & assign Function modules as mentioned in the documentation:

Hi,

I have already done this and also assigned it to the characteristics, but then also I am not getting the F4 help in CV01N transaction.

Please send the code if you have any.

Thanks & Regards

Hi Karl,

    Need your help. Have a requirement where I have to modify the F4 results in CG02. I have created the *_F4 FM and it is returning values. But instead of coming as a pop up window like a normal F4 the values are appearing in a single row in separate columns. Do you have any idea what is it that I am missing in my code?

Thanks,

Anumeha

Thanks for the answers.

Hi,

First create a function module according to the F1 documentation with import and export parameters as suggested for example: Z_EXAMPLE_CHAR.

Create a Second function module according to the F1 documentation with import and export parameters as suggested for example: Z_EXAMPLE_CHAR_F4.

Inside your CT04 Other values select function module and place Z_EXAMPLE_CHAR inside field. This will automatically call the F4 module when F4 is pressed. Note that the names must be exactly the same for both FM's except for the F4 at end. The parameters that are export with your value are Value and Values.
