We added some error message checking using Function exit EXIT_SAPLMEREQ_005. How we can bring the screen to Customer Data Tab when there are any errors under the tab. And as long as the error is not fixed, the screen will stay on the tab?
To eloborate my question - in ME51n/Me52n, the system gives a messages window/subscreen with errors or warnings upon clicking the check button or upon save. On the messages window/subscreen, we can select a particular message and edit will take action to the corresponding tab with the cursor on the field with the issue. I understand this is standard functionality.
However I'm looking for a way to make this work for a mandatory field on the customer data tab i.e., when I select the error message pertaining to this mandatory field and choose edit, control should jump to the customer data tab with the cursor on the mandatory field.
