HR and Org Model iDocs

Hi Experts

I need to do the following in CRM

1. Create Positions in the Org model

2. Relate Org Units to positions

3. Relate Central Persons to Positions and BP to positions

4. Assign users to existing BOs

So, we have tried LSMW with recordings using PP01 and PP02 but do not like this approach

We have also enabled some BAPIs but again we are not programmers so can't debug them!

We would like to do this through iDocs (called from Data Services)

I do not know what iDocs to use to do the above. Can anyone help?

Much appreciated!!
