Accoutning_line_type is 37 and not 35 when performing RMA Receipt.

Hello:

     I'm trying to customize the Costing process for RMA Receipt using CSTSCHKB.pls file CSTPSCHK package. We've requirement of changing the account segment where Accounting Line Type = Cost of Goods Sold.

     For this, I'm checking for accounting_line_type = 35 (Cost of Goods Sold) for making the change the COGS account. However, the value for accounting_line_type which is passed to this file is 37 (Cost Update Adjustment).

     But, when the distributions are generated the Accounting Type is Cost of Goods Sold.

     I would like to know why the value 37 is passed for accounting_line_type instead of 35. Also, the cost_element_id passed to this package is 0 instead of 1,3 and 5.
