O7E6 - Maintain Fast Entry Screen for GL Accounts Posting

Dear All,

I need to Text/BSEG-SGTXT field into the G/L Fast Entry screen using O7E6, however it is not available in line 1 of the list of "Possible Fields" and page down button doesnt work. Since it is not available in the "Possible Fields" list, then I can't add it into to the customised variant.

Can you please help, how to add a new field into the list of "Possible Fields" in O7E6?

Thanks a lot in advance for your kind assistance.

Regards,

Ameet
