Type ref to a table

Former Member — Tue, 12 Aug 2008 16:03:13 GMT

Hi Experts,

I have an FM returning a variable which is :

abc type ref to data.

This actually returns a table at runtime.

However since its declaration is such, I capture the reference in another variable

xyz type ref to data.

Now I need to know whether the xyz table has one row or more.

How can I do that?

Thanks and Regards,

Ravi Bhatnagar

data: v_lines type i.

field-symbols: <fs> type standard table.

ASSIGN xyz->* TO <fs>.

describe table <fs> lines v_lines.

v_liens you get the number of rows.

Try something like this. Assign the data ref to a field symbol, then use the LINES operator to find out the number of lines.

DATA: lo_ref TYPE REF TO data.
DATA: lv_lines TYPE i.

FIELD-SYMBOLS: <fs_tab> TYPE table.

ASSIGN lo_ref->* TO <fs_tab>.

lv_lines = LINES( <fs_tab> ).
