Error while Creating cost element under category 90
I have some Balance Sheet related G/L account, which I have created as cost element through transaction KA01, system gives an info message saying its an BS related account, if I ignore that message and proceed further it creates a Cost element with category (system automatically picks the category and the field gets into gray mode) 90.
We have created one more BS G/L account today and trying to create the cost element for the new G/L account, system is producing an error message:
G/L account 3200220 is a balance sheet account
Message no. KS036
Field status group R005 Material accounts is maintained
Can some one guide me to rectify this error?
Thanks in advance,
