How to set up an iDoc data transfer between R/3 en BW?

Hi all,

For reasons that are not important for my question we created on the R/3 side (ECC 4.7) a custom made transparent table. During the day data is stored / changed in this table by a custom made transaction. On a daily basis the content of the table is transferred to BW (3.5) by using a generic extraction. We now want this new / changed data to be instantly available in BW. We do not prefer a remote InfoCube but we think it must be possible to use the iDoc technology here.

Does anyone has tips, documents or perhaps a step by step solution how to do this?

Any help is welcome and will be rewarded with points.

Thnx in advance,

Henk.
