CT04 Characteristic values not getting updated

Dear Experts,

I am creating new characteristic value in CT04.The Character is REL_PDOC_TYPE. In the Values tab I added value as "IMP" and description as "IMP Service PO".

When I save system gives a message "characteristic REL_PDOC_TYPE changed". But while checking it again in CT04 it pop up a message " Express document "Update was terminated" received from author "Ilyas Ahmed" and take me in, where I could not see my data which I created.

Thank you all.

Joseph
