Validating UDF Field

Question

Dear All,
How can I validate a UDF field in Business Partner screen? As I don't want to set any default value for that UDF, I could not make it as Mandatory also. Please help me to resolve this problem.
Thanks in advance.

Hi,
The SBO_sp_TransactionNotification proc can be used for this type of validation but you could also use code in your addon. The benefit of using the proc is that this will work with BPs created using the DI API (eg DTW import or another addon).
As you are only trying to read data on a system form, you can use the DBDataSources already attached to it to check the UDF value. This is a better solution because it does not rely on the UDF tab being open. You cannot use this method to write to the UDF due to the restrictions on a system form.
You could add something like the following to the item pressed event (when BeforeAction is true) of the Add button on the BP form:
SAPbouiCOM.DBDataSource sboDS = (SAPbouiCOM.DBDataSource)sboForm.DataSources.DBDataSources.Item("OCRD");
string sValue = sboDS.GetValue("U_MYUDF", 0).TrimEnd();
if(sValue == "")
      BubbleEvent = false;
      _sboApp.SetStatusBarMessage("You must enter a value in the UDF", SAPbouiCOM.BoMessageTime.bmt_Long, true);
You'll also need to check the form mode to make sure you only validate the field when the form is in Add or Update mode.
Kind Regards,
