SAP Note 28704 - F4: Double byte systems and matchcode values

Symptom:

When extending the material number to more than 32 characters, all characters after the 32nd are truncated after selecting a matchcode value using F4 help when resetting the values on the screen.

Cause and prerequisites

The screen processor checks whether the information on the length of the value is available. If not, the value is limited to 32 characters.

Solution
The field length must be returned from the matchcode help to the screen processsor.
In Release 3.0A proceed as described below. In Releases 3.0F/3.0G use the appended advance correction.
