Decoupling of AR, AP, GL Datasources (i.e. 0FI_AR_4)

I've checked out several posts regarding the topic of Decoupling 0fi_ar_4 0fi_ap_4 from 0fi_gl_4, but unfortunatly still don't see my specific issue.

We have PI 2004_1_46c, BW 3.0b. I found an OSS note 826023 that says it decouples the extractors. Now, i thought this would remove the dependency, but we applied this and the dependency is still there.

In R/3, using RSA3, if I try to view 0FI_AR_4 data, I cannot unless 0FL_GL_4 has been loaded into BW. I have no use for GL at this time, so I really do want to remove this dependency.

ALSO, I used CMOD to add logic in the customer exit to populate zz* fields I added to the structure append. I read in another thread that I could do it this way instead of using the SAP suggested function module (from SAP documentation). However, now that I have done that, when I try to run the delta init, it just sits there. When I look at the job log (R/3), it is empty, save for some comments. Any idea why?

Any help would be appreciated!!
