Master Data Upload

Hi,

I have a Business Content object 0GL_Account that is updated daily with master data from SAP R/3 (One info package for text, One for ATTR, and one for Heirarchies.)

In this case the GL accounts have been classified in R/3 and the master data upload has gone sucessfully for all 3 instances.

However when I try to make a restricted key fig in the BEX (i select my gl a/c heirarchy and get a heirarchy grouping of accounts) about 20 account heirarchies are in the unassigned nodes section when they have been assigned in R/3 already.

Please give me any sugesstions as to why this is happening.

Thanks
