Letu2019s assume we have three roles in table Zrole_db_table : abc, acc, adc

Hi,

Simple select does this job.

DATA: l_role TYPE string.

l_role = 'ab*' or 'a*' or 'abc* (As per your input).

SELECT ...
INTO TABLE....
FROM Zrole_db_table 
WHERE type LIKE l_role.

Performance completely depends on the number of entries in your table.

Thanks,

Vinod.

HI Vinod ,

Thanks this is not exactly the issue .

assume that we have 4 roles like

A

ABC

ABD

ABCD

And user request ABC

he will get ABC and ABCD but he should get just ABC

How you suggest to handle it ?

Regards

James

Hello James,

How about trying this way:

PARAMETERS: P_ROLE TYPE CHAR30. "Use the Data Element for role (i am not infront of an SAP system)

DATA: 
R_RNG TYPE STANDARD TABLE OF SELOPT,
W_RNG TYPE SELOPT.

W_RNG-SIGN = 'I'.
W_RNG-OPTION = 'CP'.
CONCATENATE P_ROLE '*' INTO W_RNG-LOW.
APPEND W_RNG TO R_RNG.

SELECT * FROM <AGR* table> INTO TABLE ITAB WHERE ROLE IN R_RNG.

IF SY-SUBRC = 0.
SORT ITAB BY ROLE.

READ TABLE ITAB INTO WA WITH KEY ROLE = P_ROLE BINARY SEARCH.
IF SY-SUBRC = 0.
" You have the single Role you need. In this case you will get ABC :)
ENDIF.
ENDIF.

Hope i am clear.

BR,

Suhas
