ESS Bank Info - Saving banks which were marked for deletion in BNKA

Hi experts,

We're on EP 7 and ECC6 Level 20.

I have a problem here. In PA30 when we save a new entry of bank details into Infotype 0009 (Bank Details), the user exits are triggered. Our current checks include if the bank is marked for deletion in table BNKA (Field LOEVM), users will be given warning and saving will not be allowed.

However, in ESS, no error messages were prompted. We don't even see the warning message "Bank has been marked for deletion".

So is there any way that we can force it into an error message so that users are not able to choose these banks that have been marked for deletion? I don't think user exits work in ESS.

Useful information will be rewarded. Thanks.

Regards,

Damien
