Diagnosis
The input field contains prohibited characters. These are generallycharacters that your frontend can process, but which are not permittedin the R/3 database.
There can be several reasons for this:
For any language area, the number of characters allowed by ISO,Microsoft, IBM, Apple etc. is often similar but rarely exactly thesame. Frontends can often specify and display special characters inaddition to those contained in the ISO character sets.
If you are working on a frontend whose language area is not suitablefor the R/3 System onto which you have logged on, there are severalcharacters on your keyboard which cannot be used.

System Response
The R/3 System replaces these prohibited characters with otherpermitted characters and displays this error message (00.195 or00.077). The system positions the cursor in the line or field in whichthe prohibited character was found.

Procedure
If you agree with the proposal, you should re-choose the last functionkey (often [Enter].)
If you do not agree with the proposal, you should edit the data. Indoing so only use permitted characters or the system will display theerror message again.
If you cannot display texts containing characters that are permitted byyour frontend, you should end the current transaction at a suitablepoint (usually using the [Esc] key or [F12].)
There may be another frontend that is able to process these characters.
