Hi biswajit,

Very Very simple LDB program.

1. Create a new program.

2. In Attributes section,

enter PNP (in logical database field)

3. In source code, just enter,

REPORT ABC.

TABLES : PERNR.

get pernr.

write : pernr-pernr.

4. Run,

and u will get a listing of all employees.

regards,

amit m.

Hi,

Logical Database - SE36

A logical database is a special ABAP/4 program which combines the contents of certain database tables. You can link a logical database to an ABAP/4 report program as an attribute. The logical database then supplies the report program with a set of hierarchically structured table lines which can be taken from different database tables.

Reading a SAP standard logical database (DB M - MRP Documents) in your ABAP/4 program.

start-of-selection.

get is equal to select * from....

get mdkp.

check field-name.

get mdtb.

check field-name

end-of-selection.

Hi again,

1 can we create ur own logical database name instead of using standard one(like pnp)??

Yes absolutely.

2. SLDB is the tcode.

3. Also read documentation on logical database,

to get an idea of the components involved in it.
