BDC FBV1 Additional Data screen SAPLF040 0330 problem

[jim_varrati]

Hello experts I've been stuck at this problem I was wondering if someone can shed some light I've been researching and coming up short.

I developed an invoice upload program that parks invoices via BDC FBV1. Everything is working fine except when I need to populate the ref field XBLNR for some gl entries. When the program executes the following nothing happens.

             PERFORM bdc_dynpro      USING 'SAPLF040' '0330'.

             PERFORM bdc_field           USING 'BDC_CURSOR'

                                                                'BSEG-XREF3'.

             PERFORM bdc_field           USING 'BSEG-XREF3'

                                                                wa_ap_temp-xref3.

             PERFORM bdc_field       USING 'BDC_OKCODE'

                                                                               '/00'.

I can watch everything in step mode 'A' it just stops and and waits for the screen to change, If I push the additional data button the program continues on.

I can't figure out how to change this screen it is not responding to the obvious.

Any ideas?

thanks in advance

Jim
