BDC programming using Batch input Session.

Former Member — Mon, 07 Apr 2008 01:29:06 GMT

Hello Experts.

I'm an ABAP beginner. I've benn practicing BDC programming using Batch input Session

at the moment.

This is the program that upload Local file which has plural records, and put the records into a Session.

These are the records.

413459,KIM EI HWAN121 ,19810607,MIADONG1234

423459,KIM EI HWAN122 ,19810607,MIADONG1235

433459,KIM EI HWAN123 ,19810607,MIADONG1236

443459,KIM EI HWAN124 ,19810607,MIADONG1237

453459,KIM EI HWAN125 ,19810607,MIADONG1238

463459,KIM EI HWAN126 ,19810607,MIADONG1239

I succeeded making Session.

However, for some reaseon, every record in the Session has got the same, value which is the first record.

Why is this happening? And How can I correct the code below?
