0FI_GL_14 Delta extraction

Hello Masters,

I am trying to fetch FI GL data using extractor 0FI_GL_14 via BODS. However I am facing some issue with extractor when using for delta load. So the scenario is like:

-> I posted some FI documents

-> I run BODS job to get delta load - I am able to get the newly created document data in staging table and in RSA7 I can see that data

-> After 1 hour or more I run my BODS job again - I get the same document data although no changes are made for that document and in RSA7 there are now duplicate entries for that document

-> Now I run my BODS job for the third time - that document data is not fetched this time

Now my issue is that why I am getting duplicate entries. Any help will be appreciated.

Regards

Gaurav
