Hierarchy Extraction of FI-SL Set with Compounding - Conversion Errors

We need to extract a hierarchy for G/L Account based on sets created in R/3 Transaction GS01 (set class 0000). I have used R/3 Transaction BW07 to create the data source. The BW InfoObject 0GL_Account is compounded with 0CHRT_ACCTS.

SAP Note 134975 says to execute compounding in a customer exit. We have created a project for the SAP enhancement RSAP0001 and implemented program ZXRSAU04. Do I need to add any code to this program? (The note refers to an attachment, but there is no attachment to note 134975.)

When I extract the hierarchy to BW, I get an error in the second step of the process -- "start update of master data hierarchy." The error is "The technical node name for node id 00000002 is not consistent for conversion exit ALPHA , which is stored with InfoObject 0GL_ACCOUNT ." I have checked the Conversion box for 0GL_Account in the transfer rules, but still get the error.

Anyone able to help?

(Note: If I create the data source without compounding, I can extract it successfully, but then all GL Accounts fall into the Unassigned category because they don't have any values for the compounded InfoObject Chart of Accounts.)
