Screen flow logic

[Former Member]

Hi.

I need some help. I've never worked with screens until now.

I have created a custom field in tab Basic Data 1 in t-codes MM01/MM02/MM03 ; also i have created a field in MARA table.

When i make some changes to this field in MM02 or when i want to add new text to this field the value it's not saved in MARA table. More, in MM02 if i write some text in this field, and if go to tab Basic Data2, when i return to tab Basic Data 1, this field is cleared (field has no value, is empty).

And , in MM03 (display mode) all fields except this customer field are disabled (grayed).

So, how to solve this problems?

Please someone help me.

Thanks in advance.

Hi,

You need to handle the custom fields in PBO and PAI of the screen exits. There are customer exits available in PBO and PAI of that screen. Write your code in these exits.

Thanks,
