ABAP CODE

[Former Member]

Hi ,

Can anyone please explain what the code below does. It is one that is used in infopackages for dynamic update of selection fields. i want to know the logic behind this code.Thanks in advance

Dave

data: l_idx like sy-tabix.

read table l_t_range with key

fieldname = 'OPTIONSETNAME'.

l_idx = sy-tabix.

RANGES:

gr_reso_optionset FOR l_t_range-low.

CALL FUNCTION 'Z_GET_TVARV_VARIABLE_VALUE'

EXPORTING

VARIABLE_NAME = 'Z_SCC_SPA_CDM'

• IMPORTING

• NUMBER_OF_VALUES =

TABLES

VARIABLE_RANGE = gr_reso_optionset

EXCEPTIONS

VARIABLE_NOT_FOUND = 1

INVALID_RANGE_TABLE = 2

OTHERS = 3.

IF SY-SUBRC <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

loop at gr_reso_optionset.

shift gr_reso_optionset by 3 places.

l_t_range-low = gr_reso_optionset.

l_t_range-high = gr_reso_optionset.

append l_t_range.

endloop.

p_subrc = 0.

post the code of the Z function otherwise we would all be guessing!

i GUESS THAT IT IS SETTING UP THE RANGE variable from VALUES from the TVARV table based on the name 'Z_SCC_SPA_CDM'.

i.e. it gets all values from TVARV for this name and puts them in the range variable.

Hi !

I think something like the following is goning on....

- The FM 'Z_GET_TVARV_VARIABLE_VALUE' is reading the

SAP parameter Table TVARV for the parametername

'Z_SCC_SPA_CDM'

- It gives the values (as used in a selection screen) back in the table variable gr_reso_optionset

- The loop shifts the parameters value by 3 places

(why ??) and puts the shiftet values to the

variables l_t_range-low and l_t_range-high of the

internal table l_t_range.

- The loop is obviously only used to do the shifting.

Some points would be nice if that helped a bit.

the shift left is being used to 'ignore' the sign and option components of the range. Why it just doesn't refer to the 'low' I don't understand but that's what it's doing.
