R12855 reflecting error as well as calculating depreciation

Hello Team,

We are in 9.1.4 and have been reported with the following question and would like to know the cause of the same :-

1.     When we run the depreciation program (R12855) in proof mode for few assets the report is reflecting standard error 044C - Inactive Subledger Entered for which Oracle has given following explanation which is unable to understand. As check the subledger tagged against the asset with subledger type as 'C' are all active subledgers.

In 9.1 there is a work around program that allows the inactive flag to be changed, but it is only for E1 9.1 and future releases of the software. Refer to General Overview of Work Order Mass Update (P48022, P48714, P48710, P13714, P17714, P15248, R48714)
