Help: Read table structure

[Former Member]

Hi everyone

is it possible to read a table structure of a intern Table to check whether in this table some specific data field exists or not. for example ,to check table1 if matnr is a data field in it.

the best will be using a loop to check all data fields name and type.

anyone can solve this problem???

thanks !!!

Here is how you can do this.

Sample code.

DATA: BEGIN OF it OCCURS 0,

vbeln LIKE vbap-vbeln,

posnr LIKE vbap-posnr,

END OF it.

FIELD-SYMBOLS: <field>.

ASSIGN COMPONENT 'MATNR' OF STRUCTURE it TO <field>.

sy-subrc = 0 --> Means there is Matnr in the structure

sy-subrc = 4 --> Means there is NO Matnr in the structure

In the above case return code should be 4.

Hi Wang..

once you get the into your internal table..

just loop the table for searching..

and regarding the performance

you can follow the follow this steps:

1) first short the table with MATNR

2) pass all the varible to some another table.

or

just first pass the table to another table.

and delete all the records where matnr NE your MATNR.

it is all just for performance.. only

Thanks and Regards,
