Problems modifying a itab

Former Member — Wed, 29 Dec 2010 08:47:32 GMT

Hi all.

We are enhacing the tcode vfx3 report adding new fields. At this point we have added 2 fields (netwr and mwsbk) by the use of a user exit. Everything is ok.

Now we want to add a new field(mrnkz 'char 1'), the steps we follow are the same as we followed before, but now it is not working properly.

CODE:


"loop sobre la tabla
LOOP AT c_vmcfa.
  READ TABLE it_struct INTO lwa_struct WITH KEY vbeln = c_vmcfa-vbeln.
  c_vmcfa-netwr = lwa_struct-netwr.
  c_vmcfa-mwsbk = lwa_struct-mwsbk.
  c_vmcfa-mrnkz = lwa_struct-mrnkz.
  MODIFY TABLE c_vmcfa." TRANSPORTING netwr mwsbk mrnkz.
  CLEAR c_vmcfa.
ENDLOOP.

We are having problems when the value of lwa_struct-mrnkz contains a 'X'. In this case, the modify throws an exception. When the value of lwa_struct-mrnkz isn't a 'X', the line is modified properly. The exception thrown is:

"Object SDBLBDDL of class RE and language EN does not exist. "

How can i solve this problem? Is this a documentation problem?.

use index for modifyin the table.

like;

LOOP AT c_vmcfa.

data; lv_index type sy-tabix.

lv_index = sy-tabix.

READ TABLE it_struct INTO lwa_struct WITH KEY vbeln = c_vmcfa-vbeln.

c_vmcfa-netwr = lwa_struct-netwr.

c_vmcfa-mwsbk = lwa_struct-mwsbk.

c_vmcfa-mrnkz = lwa_struct-mrnkz.

MODIFY TABLE c_vmcfa index lv_index." TRANSPORTING netwr mwsbk mrnkz.

clear lv_index.

ENDLOOP.

Thanks

The problem was in the MODIFY statement. I couldn't see the INDEX statements only works with MODIFY, without TABLE. And i couldn't see it.

Thank's.

Looks like some data type mismatch. What is the data type for MRNKZ?
