Can we load delta for FIGL extractors twice in 24 hours

Hi gurus,

We perform delta-loads twice a day for the datasource 0FI_GL_4. However, only during the first delta-load are records

fetched and transferred from R/3 to BW. The second delta-load during the day always gives as result 0 records.

How to overcome this situation..

Please help.

thnx,

Sunita
