dynamic internal table fields

Former Member — Tue, 30 Dec 2008 09:39:33 GMT

i am trying to find a way to gennerate dynamic internal fields.

i am trying to get the amount posted for each month basing on accounting docs' posting date.

suppose i am running report on aug month output too should give 8 cloumns likwise sep.. output should show only 9 columns.

I could create internal table with 12 fields(one for each month), but if i run the report for Jan to Aug, only 8 fields will have data and rest of the fields will show empty. so i want to generate the internal table fields dynamically.

is it possible? Just an idea for betterment rather than the regular programming practise.

Instead of creating dynamic internal table, it would be easier to dynamatically create the field catalog based on the month you are generating the report.

your part of the code is present in routine

perform dynamic_table.
