Changing LDB

[Former Member]

Hi Experts,

I have a Z report which uses Logical Database. In LDB, it define the selection screen fields too. I need to make those fields as mandatory. LDB name is SAP Standard. There I find Selections tab, where the selection screen fields are defined. As it is SAP Standard, how do I make changes in it.

Urgent. Plz help.

Thanks.

hi,

Since your program is a 'Z' custom one. Copy the standard LDB to a 'Z' custom ldb, make the changes and assign to your 'Z' program.

Hi,

Do the vgalidation for the field if you want to make it mandatory.

AT selection screen.

If p_fld is initial.

msg e000 with 'Please enter the value'.

If it is initial, it will throw a message. If a value is entered LDB fetches the data accordingly

Thanks,

Keerthi.
