Dear forum,

I have the scenario where i need to restrict the loop from the select-options.

in the select-options, user enter currency.

then in the loop i need to loop base on the currency user enter.

may i know what steps should i use for the loop as loop cannot support where.

thanks

HI Gengis

I have the scenario where i need to restrict the loop from the select-options.

in the select-options, user enter currency.

then in the loop i need to loop base on the currency user enter.

may i know what steps should i use for the loop as loop cannot support where.

as per your requirement.

you have some data in your internal table also you have a select-options to input values.

on the basis of the values in your select option you want to fetch the values from your internal table. right???

then there should be a field like your select option in your internal table.

select-option: s_matnr for mara-matnr.

let assume you have an internal table with matnr and other fields also and your select-options is for mara-matnr.

then you need to select the values in your internal table according to the values in your select-options like below.

SELECT MATNR field1 field2........ from dbtable into table itab where matnr = s_matnr.

the above code will give you the values matching the values in your select-options.

you need not to apply loop becasue you already have only those values for which yo u have found records in the DBTABLE.

in case you want to apply loop on an internal table on the basis of s_matnr's values, then you can write.

in this scenario you need to define 2 internal table one with already fethced values and another in which we will fetch the values according to select-options.

loop at itab into wa_itab.

read table itab1 into wa_itab1 where matnr = wa_itab-matnr.

write statement........

endloop.

before that youwill have to fetch values in itab according to s_matnr.

I hope this will clear your query.

Hi Gengis,

Firstly please be informed that LOOP does support where condition.

Lets say your a) internal table is it_tab,

b) work area is wa_tab and

c) select option is s_currency.

and Currency is a field in the internal table.

The syntax would be:

Loop at it_tab into wa_tab where currency in s_currency[].

XXXX

YYYYYY

Endloop.

Hi,

You can do in the below way.

option 1 :

loop at you select -option as it is internal table with header line you can loop it and then

read your internal table in which you have values.

ie

loop at select-option.

read table itab ino wa_itab with key feild = select-option

if sy-subrc = 0 .

do your required processing.

endif.

endloop.

option 2

loop your itab with where condition on select-option

Let me know if you need further information
