Table maintainance generator with DEC field

Hi All,

I have a problem in creating table maintainance generator for a custom table.

my custom table has four fields and the third field is a DEC field and others all fields are CHAR fields. when i am creating the Table maintainance generator with one step then in SM30 table maintainance i am able to see all the fields. But when i am creating the table maintainance generator with two steps the on overview screen i am able to view first and second fields only, the DEC field and the following fields are not been generated on the first screen but i am able to see all of them on the second screen.

Kindly provide the solution to it. Really appriciated.

Regards,

Waliullah Mohd.
