The account hierarchy master need to be loaded month, I have a GL account number A_1234566 which has parent A_123 in BW, the first time when I loaded the hierarchy, it success, therefore it will have node A_123 in the PARENTH1 column in my excel master data, however, when O run the loading hierarchy package next month, I receive "Dimension member A_1234566 has multiple parents in PARENTH1" error message.
I check the BW master data for account, there is nothing change for account A_1234566,Anybody know why this happen and how to fix it?
Thanks.
