Trying to make text fields mandatory, I am using the Properties IsRequired (in combination with IsRecommended).
SAP Help says: IsRequired = Indicates whether user input is required for specified field. It is not possible to leave the current screen if at least on required field is not entered.
The values set to TRUE do not seem to make the fields mandatory for input.
More info: it's a textfield, created in Personas. The 'checkmark' to indicate it's mandatory is shown.
Saving the transaction without entering a value is possible without warning.
Anyone who can point me at the right direction?
