We hada requirement to restrict the users from entering japanese caharaceters in the reference field of a accounting document. The validation for this was done using the transaction OB28. when the user posts the accounting document using transaction FB01 or changes the accounting document using transaction FB02, the validation provided in OB28 does work(it throws an error restricting the user from entering japanese characters if he has done so). But whenthe user pots the accounting document using the transaction FB50, the same error message comes as information message although the coding is for giving an error message.
This however does not happen when the user logs on in English. In English logon the error mesage does appear.
When the user logs on in Japanese the message comes as an information message but at the same time does not allow posting of the document.
Debugging this revealed that the OSS note 197329 has been applied to the standard SAP program SAPMF05A.
Any pointers to how this can be rectifiied would be appreciated.
Thanks in advance.
