Problem with data type 'STRING'

Question

Hi All,
I have created a table named as zproject_mat and there is a field 'LONG_D' for long description and its size is not limited, so i used 'STRING' data type for this field. But the problem is: when i use this field in where condition with 'SELECT QUERY'  in my abap program , it throws me an error..'The field long_d is a long string , so it cannot be used in WHERE, ON, or having conditions'.
Can anyone help me regarding this. I dont know which data type will be suitable in both conditions, LONG DESC AND SELECT QUERY.
Regards
Rahul

Hi Rahul,
As mentioned your Table name is 'zproject_mat' and there is a field 'LONG_D'.
The field 'LONG_D' will have a Data Element associated with it. Create a new input Data Element & Domain 'ZLONG' of Type CHAR with Length = 1100. This will used in the code.
For the Table 'zproject_mat', you need to need to break up your field as 'LONG_D1', 'LONG_D2', ........, 'LONG_D5' with Data Element as 'BAPI_MSG'.
To INSERT data in table:
In your code, you need to write your logic where the field 'LONG_D' is SPLIT into 5 words and saved in your table against the 5 fields.
To SELECT data from table:
In your code, again you need to write your logic where the field 'LONG_D' is SPLIT into 5 words as abaove and pass them to your SELECT query...
SELECT SINGLE *
FROM zproject_mat
INTO wa_zproject_mat
WHERE long_d1 = v_split1
      AND long_d2 = v_split2........
     AND long_d3 = v_split3.
The limitation of a table length is 4096 whereas of a field is 255 to make it RFC compatible. Table/Structure fields that are passed via RFC for integration have this limitation and to maintain database standards, these limitations exist.
Hope this helps.
