SM30 field validation

0 Kudos
294

Hi all,

I have a custom table, in which two fields are there 'Available Budget' and 'Balance budget'

If I am going to change available budget from this table, then balance budget is as follows.

Balance Budget = Available budget - Used amount.

Here data is validated against "used amount" which is maintained in another custom table.

Now while updating or creating new entries in sm30 how to validate the above..

I tried using SM30 'Before save event', the data is not getting modified to display in table

please suggest, it will be helpful if sample code is available

  1. Did you use the sample code provided by SAP for this event
  2. Are you sure that dialogue maintenance is the right tool for this type of development?
