Data no longer available when SALV_WD_TABLE GET_MODEL called
Hi DynPro Gurus,
I'm very new to ABAP WebDynpro, i could consider this would be my first program.
I'm not sure whats wrong with the code below but I'm getting the error as in the subject field.
Has anyone encountered this problem before? How can i resolve this problem? Please help.
Thank you.
