modify database table(staandard)

Hi,

GB01 is the database table.

GB01-BOOLCLASS = 009

GB01-CLASSTYPE = S

GB01-BCLTAB = BSEG.

GB01-BCLFIELD = GSBER.

Upon input of above details, will get table Record as

BOOLCLASS 9

CLASSTYPE S

BCLTAB BSEG

BCLFIELD GSBER

BEXCLUDE X

In the record, the field GB01-BEXCLUDE has the value “X” in it. It should be replaced by value “=.”

Changes should be made ONLY for this record. Other Records should not be touched.

How can we do this. Help me in doing this.

Thanks,

Ramya.
