Problem with Dynamic internal table

Former Member — Tue, 20 Jun 2006 08:01:46 GMT

Hello All,

Actually my requirement is, I have to download a textfile to the application server.

The file should contains the columns which the user saves as a layout variant of the ALV list display.

So I have called the FM 'REUSE_ALV_VARIANT_SELECT' to find out the hidden fields. Then with the visble field I have created a dynamic internal table.

<b>I a getting the problem here only.</b>

After creating the dynamic table, The data in my outtab is not moving properly to the dynamic table.

For example

If the list has F1,F2,F3,F4,F5 as five fields.

But the user selects only F1,F2,F5 as saves as alayout variant.

So in the output file it should show the column F1,F2 & F5.

But in my case, the F1,F2,F3 is moving to the field symbol.

This is because I am not able to use Move-coreesponding syntax.

I have attached my code: here

As MOVE-CORRESPONDING is not working, then what you are doing using the ASSIGN COMPONENT is the right way to go.

However, you can try doing this also as dynamic. The field selection is dynamic you will have the field names some where. Get those variables

ASSIGN COMPONENT (VAR_NAME) ....

If you have created your dynamic table using catalog table, you should use it to transfer the data with a code like this:

LOOP AT IT_OUTTAB INTO WA_OUTTAB.

LOOP AT G_T_FIELDCAT INTO G_R_FIELDCAT

WHERE NO_OUT IS INITIAL

AND TECH IS INITIAL.

ASSING COMPONENT G_R_FIELDCAT-FIELDNAME OF STRUCTURE WA_OUTTAB TO <FS>.
