Its possible by creating multiple variants. Follow those steps:

1. Create an extractor with full load delta type.

2. Create multiple variants with different selections. All variants combined must cover all data. For example if we do selections on a field containing year, we need to have variant for each year.

3. Run extraction for all created variants.

If you want to use some delta mechanism for extraction after full load follow those steps:

1. Add global setting to allow delta value reset. This can be done in transaction /DVD/RL_TM. Choose table /DVD/GL_CUS_VALS and add setting ALLOW_DELTA_VALUE_RESET.

   Open

   

2. Create another extractor with desired delta type(same source and target as the first full load extractor).
   
   

3. Go to delta tools

   Open

   

   manage tab.

4. Edit delta value to last value which was extracted. For example if we did full load using variants with selections on a field containing year, we need to set last year in selection as the value of delta.

5. Perform delta run only from manage tab. Do not execute variant directly because full load would be done again as it would be first execution of extractor.
