Cost Centers not appearing in the GL Display FAGLL03

Dear Friends,

In case of a particular GL Account we find tha the Cost Centers are not getting displayed in the GL Account display. However, when we check the documents, we find that the Cost Centers have been maintained in the document entry. The users have selected the field Cost Center thru Change Layout, but the report still does not show the Cost Centers.

Could you help and advise what needs to be checked.

Regards,
