Need a generic data type to hold any string

[Former Member]

Hi,

I m trying to write a program which can log data from any table into a Trace Z table.

I have used

FIELD-SYMBOLS: <line>.

to get the line of that table. But now I want to dynamically know what are the field names of this line structure and the data in it. And then write it as a string to the trace Z table

form log_table_data tables rt_any_table

using rv_statement type string.

data: v_line type string,

v_char_line type char255.

FIELD-SYMBOLS: <line>.

loop at rt_table ASSIGNING <LINE>.

v_char_line = <LINE>. - Terminating at this statement

• ASSIGN <LINE> to v_line casting type string.

endloop.

endform.

Thanks for reading

Hi,

if you are interested in generic programming in ABAP then this [presentation|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b332e090-0201-0010-bdbd-b735e96fe0ae] is full of information. There is a class CL_ABAP_STRUCTDESCR with method GET_COMPONENTS. This method returns a list of components of table or structure. So you will be able to loop over every field in the table and convert each field into string.

Cheers
