HI Experts ,

I've the following issue.

I've created a FM in which it_char is import parameter

data : it_char type ztest

where ztest is table type .

now the issue is that when I run code inspector I get an error has bellow when I do this,

SORT it_char by atnam.

READ TABLE it_char INTO lv_chara WITH KEY atnam = lwa_allocvaluesnum-charact .

ERROR is

you may only read from table "it_char".

now how can I remove this error ???

Regards,

Suhas

it_char is an import parameter. So you can't change it's value. If you sort a table, you're changing it. If you want to change it, make it a changing parameter.

Hi Suhas,

I think its coming because you have put it in importing parameters which is used for variables or structures only. Try putting the table it_Char in changing parameters or better in Tables parameters.

It should work.

Hi,

Define table type ztest in fm and assign Import value to that and do any operation on that.

I remember, when we use READ table WITH KEY option, then the it_table should be defined with Key..

So, I would suggest

1. Pass the internal table as table parameter,

2. Inside the function, crete another it_table with key option

3. assign the pased table parameter it table to this above defined it_table.

4. then use the REad statement on the newly defined it_table

No it isn't. You can quite happily pass tables in the importing, exporting or changing parameters. In fact, if you try to use TABLES, you'll get a warning about them being obsolete.

The problem is with the SORT. I just created a test, and it's syntax error in 7.01.

It is the SORT causing the problem - not the READ.

I agree with Matthew Billingham, you cannot execute any sort/modify statement on an import parameter, so either define it as a changing parameter or copy its data to a local internal table that you will be allowed to sort/modify.
