String Functions in SAP BW

String Functions in SAP BW

while we are extracting data form ECC/Third party tolls  to BW we got the some time special char errors . if we use the sting functions we aviod the special char issue errors.

1.Shift

2.Replace

3.Transalate

4.Concatenate

5.Condense

6.Split.

1 SHIFT – shift will move the char string by default left by 1 position.

Ex- 

DATA : V1 TYPE STRING,
       V2 TYPE STRING,
       V3 TYPE STRING.
V1 = 'ABAP'.
V2 = 'OBJECTS'.
V3 = 'HARD WORK'.
SHIFT V1 BY2PLACES.
SHIFT V2 RIGHT BY2PLACES.
SHIFT V3 CIRCULAR BY4PLACES.

WRITE:/ V1,V2,V3.

Program output

2. REPLACE - Replace will replace the set of chars with another set of chars in a char string.
Ex-

data : text1 type string,
       text2 type string,
       text3(16) typec.

text1 = 'ABCDEFGHABCDEFGH'.
text3 = 'ABCDEFGHABCDEFGH'.
text2 = 'ABCDEFGHABCDEFGHABCDEFGH'.

WRITE /: TEXT1, TEXT3.
REPLACE'D'IN TEXT1 WITH'XYZ' .
REPLACE'D'IN TEXT3 WITH'XYZ' .
WRITE:/ TEXT1, TEXT3.
SKIP.
WRITE :/ 'BEFORE:', TEXT2.
REPLACEALLOCCURRENCESOF'DE'IN TEXT2 WITH'XY'
WRITE :/ ' AFTER :', TEXT2.
SKIP.

Program output

Note -

Write statement – print the record.

SKIP – it will skip the one line.

3. TRANSLATE – translate to upper case to lowercase and lower case to upper case.

DATA : TEXT4 TYPE STRING,
       TEXT5 TYPE STRING,
       TEXT6 TYPE STRING.

TEXT4 = 'abcdefgh'.
  text5 = 'ABCDEFGH'.
  TEXT6 = 'AbcDEfGh'.

WRITE:/ 'BEFORE:', TEXT4.
  TRANSLATE TEXT4 TOUPPERCASE.
  WRITE:/ 'AFTER:', TEXT4.
  SKIP.
  WRITE:/ 'BEFORE:', TEXT5.
  TRANSLATE TEXT5 TOLOWERCASE.
  WRITE:/ 'AFTER:', TEXT5.
  SKIP.
  WRITE:/ 'BEFORE:', TEXT6.
  TRANSLATE TEXT6 TOUPPERCASE.
  WRITE:/ 'AFTER:', TEXT6.

Program output

4. CONCATENATE – it will merge more than char string into one char string.

DATA : CTEXT1 TYPE STRING,
       CTEXT2 TYPE STRING,
       CTEXT3 TYPE STRING.

  CTEXT1 = 'RAMA'.
  CTEXT2 = 'KRISHNA'.

CONCATENATE CTEXT1 CTEXT2 INTO CTEXT3.
WRITE:/ CTEXT3.

Program output

5. CONDENSE – it will remove the leading spaces.

DATA : CTEXT8 TYPE STRING,
       CTEXT9 TYPE STRING.
CTEXT8 = ' ABAP OBJECTS'.
CTEXT9 = ' ABAP OBJECTS'.
SKIP.
WRITE:/ CTEXT8.
CONDENSE CTEXT8.
WRITE:/ CTEXT8.
SKIP.
WRITE:/ CTEXT9.
CONDENSE CTEXT9 NO-GAPS.
WRITE:/ CTEXT9.
Program output

6. SPLIT – it will split one char string to many char string but should be the separated by unique special char.DATA : LV_TEXT6 TYPE STRING,
       LV_PROF TYPE STRING,
       LV_CAREA TYPE STRING,
       LV_CCENTER TYPE STRING.
LV_TEXT6 = 'ABCD&VA00&XYZZ'.
SPLIT LV_TEXT6 AT'&'INTO LV_PROF LV_CAREA LV_CCENTER.

WRITE:/ LV_TEXT6,
        LV_PROF,
         LV_CAREA,
          LV_CCENTER.
Program output

Note -

Write statement – print the record.

SKIP – it will skip the one line.

Hope it wil help.

Thanks,
