Hi,

Find out if you can pass any primary key while selecting the data from mseg.Keeping performance issues in mind it is always advisable, not to hit the same database table twice and you are hitting it twice.Check out if possible for you to retrieve all the data from MSEG once into a internal table.

Also Select * from dtab into correspondind field is not recommened from performance point of view.So while retrieving the data try to use an internal table with the same structure for the fields you are selecting from the table.

For how to improve the performance by keeping the same code, for all the Indexes already present in the table find out whether you can pass one more field from the index or not.If not than you can go with creation of indexes.But generally as far as possible try not to create a new index.

Reward if useful

Hi,

You can use Material Document year to restrict the entries in the select query or still if it is timing out you can try to run the report in back ground and then retrive the result from the spool once a year report are moslty run in back ground as they have huge amount of data and simple select query may take a lot of time to work causing a time out .

Hi

MSEG table contains lot of data and you are fetching it based on just ebe;ln field

why can't you write a single select statment by joining MKPF and MSEG and then seggragate the data into different internal tables based on your conditions.

select

a~mblnr

a~mjahr

a~blart

a~budat

b~bwart

b~matnr

b~erfmg

b~ebeln

b~werks

b~lgort

b~lfbnr

b~smbln

from mkpf as a join mseg as b on a_{mblnr = b}mblnr and

a_{mjahr = b}mjahr

into table itab

a~budat ( between date1 and date2 )

and a~mjahr = s_year

and a~blart in ('WA','WE','WL')

and b_{bwart in ( '101','531' ,'102','532' ) and b}werks = s_werks.
