Select data from F4 help only from table and error while incorrect data entered manually

Former Member — Mon, 01 Feb 2016 09:40:11 GMT

Dear all ,

I have added user fields in network activity in project system , however i have created Ztable and Table maintenance for SM30. but problem is user can enter data manually (which is not maintained in table ) and save the project.

Here i want to populate data which is only available in Table field with F4 help otherwise system should pop up error.

i have used class builder and FM : F4IF_INT_TABLE_VALUE_REQUEST .

Hi Swapnil

Why don't you check this in your program? For example, when a user-action happens. You can stop the execution of the action if the entry is invalid.

Another UI-side solution I can think of:

1. Make the field read-only

2. Place a button, e.g. "Select", next to your input field, which -when clicked- shows only the available values and lets the user select one.

I have seen examples where developers did not add an extra button and expected users to click the search help button or hit F4 of the read-only field. However, I would not recommend this as it is not intuitive.

Hope this helps.

Hi,

Change the field to a drop down list and populate the list using the VRM_SET_VALUES function module. The user can then only select valid values or blank.
