Use the datat Type

LCHR

LRAW

for more number of CHAR fields like 500 and 1000

see the EDID4-SDATA field as an example

We can declare in a program as STRING

but in tables it gives error.

so better use the above data types

Hi,

Hi,

SAP wont allow declare field of string in the DB table and you can use char length of 300 CHAR300 instead of the same

Hi,

Here is the sample code to store the xml file into ABAP DB table.

First create a table called YTEST_BIN with following fileds.

Now create a program to read the XML file from your desktop and load it into the table.

Hi,

the dictionary type STRING can only be used in DATAELEMENT, STRUCTURE and DOMAIN. ABAP doesn't support to allowing STRING data type directly to the table fields.

Character string with variable length This data type can only be used in types (data elements, structures, table types) and domains. In the Dictionary a length can be specified for this type (at least 256 characters). It may be used in database tables, however, only with restrictions. For a description of them refer to the documentation of the ABAP statement 'STRING'

regards,

Ashokreddy.

Thanks Anji and Kostas,

ACTUALLY THE MAIN PROBLEM THE LENGTH THAT THE FIELD IS GOING TO TAKE IS LESS THAN 256 AND SOME TIMES MORE THAN 256.

which is better DSTRING or lraw.

siri.

If your field is not going to be bigger than 1000 characters it won't be a problem whatever field you choose. If your field is bigger than 1000 character you have to use dstring.I have worked with type dstring and it is very useful to store big info( i had used it for storing text history ) but it will be a little problem if you want to display it in an alv or something. You choose.

Siri,

I work on 4.7 and i can use dstring as data element without problems.Which version do you work on?

Kostas

Re: data type STRING

Former Member — Mon, 18 Jun 2007 11:54:46 GMT

4.6

I don't know if it is going to work in 4.6 but give it a try. Create a z data element and in the domain enter string. If this won't work in 4.6 maybe you should consider the solutions mentioned from the other people.
