Hi~~ let me ask you something.

Sometimes, I can see the code like this.

TABLES: VBAP, *VBAP,
        VBAPD, *VBAPD,
        VBPV,                          " Produktvorschlag
        CABN,                          " Merkmale
        CABNT,                       " Merkmalsbezeichnung
        CEPCT,                         " Profitcenter-Text
        *COBL, COBL,                   " Kontierungsblock

Hi, as I know, you can seem the *VBAP as another work area same to TABLES: VBAP.

After defined them,

TABLES: VBAP, *VBAP.

you can use *VBAP just like the way you use VBAP.

You can reference some standard application of SAP, like SAPMV45A.

Hope it will be helpful.

What zhenglin said is right.

SAP standard code uses a lot of variables to store current data, old data, etc. So u will mostly see vbap and *vbap.

It is as good as vbap and vbap1.

Hello Kyung Woo,

This is one of the undocumented ways of data declarations. As I had mentioned in , the * notation is used to contain the temporary values for a table work area.

This need not be limited to the Standard SAP Code. In your programs you would very often declare temporary work areas like -

tables vbak.
.
.
data lt_vbak like table of vbak.
data ls_vbak like line  of vbak.
.
.
.
data ls_temp_vbak like vbak.
.

It might be a good idea to have <b>*vbak</b> instead of <i>ls_temp_vbak</i>. That of course depends on the naming conventions you would want to follow for all your custom developments. It is just a convenient and more readable way of declaring the temporary structure.
