Hello,

Is there a way to restrict Users from entering Special characters in the Invoice number field? For instance, when End Users input special characters in the Invoice # field, then, D365 will prompt the User that /special characters' cannot be entered.

Hi

i think you can use the regex on validateWrite method

e.g.

public boolean validateWrite() { boolean ret; TextBuffer txt = new TextBuffer(); ret = super(); // if extension use next validateWrite() txt.setText(this.InvoiceId); txt.regularExpressions(true); if (txt.find("^[A-Z 0-9]+$")) { ret = true;//info("string contains only numbers"); } else { ret = checkFailed(strFmt(" Conatin the Special Character")); } return ret; }
