Splitting Select Options

Question

Hi All,
I am facing a problem in splitting the Select options for my screen. What I have to do is I am expecting the User to enter around 5000 records in the Select Options. I have to use 2000 records at a time for processing, which means three set of records of 2000, 2000 and 500.
Can you please tell me how can this be achieved??

Answer 1

Are you sure that even reducing the SELECT-OPTION to package of 2000 will be enough, in some database the system will raise an error related to a too large SQL statement.
Splitting an internal table (as SELECT-OPTIONS are) is very easy. (see bellow)
But be aware that some records may be exclusions, like :
- SIGN = 'E' and OPTION is one of the positive operator like EQ, BT or CP
- SIGN = 'I' and OPTION is one of the negative operator (every operator except the three previous)
Those records must be in every package of selection
so loop at select-options
- put the exclusion in a first internal table
loop once again at select-options excluding the records of the previous loop
- append to a temporary internal table
- when number of record equal maximal number allowed for a SQL SELECT minus the number of record in the first internal table, execute the SELECT, clear the temporary internal table
To bypass this problem
- don't use those record to build the partial select-options but delete records after select from database
- You could(should) consider restricting select-options allowed options ([SELECT_OPTIONS_RESTRICT|http://wiki.sdn.sap.com/wiki/display/Snippets/RestrictSelectOptions]) so you wont have to execute this and only have to split an internal table with statement like [APPEND|http://help.sap.com/abapdocu_70/en/ABAPAPPEND.htm] [LINES OF jtab [FROM idx1] [TO idx2] |http://help.sap.com/abapdocu_70/en/ABAPAPPEND_LINESPEC.htm#&ABAP_ALTERNATIVE_3@3@]
