GOAL

Question: We need to change the Charge type for OSP resources from PO Move to PO Receipt. While doing so, we have noticed that the Absorption & Variation accounts are updated which is not expected.
why does this occur? How are the accounts derived in the BOM Resources form? 
 

SOLUTION

Answer:

In the BOM > Resources form , when the Charge Type is changed the procedure get_default_accounts is triggered and the accounts are set as the default ones.
The Absorption Account is set as default with value defined in RCV_PARAMETERS

The Variance Account is set as default with value defined in MTL_PARAMETERS

Resource form - BOMFDORS.fmb

procedure get_default_accounts is
 X_absorption_account_holder NUMBER=-1;
 X_rate_variance_account_holder NUMBER=-1;
begin

 SELECT RECEIVING_ACCOUNT_ID
 INTO X_absorption_account_holder
 FROM RCV_PARAMETERS
 WHERE ORGANIZATION_ID = parameter.org_id;

 SELECT PURCHASE_PRICE_VAR_ACCOUNT
 INTO X_rate_variance_account_holder
 FROM  MTL_PARAMETERS
 WHERE ORGANIZATION_ID = parameter.org_id;

Note: These account default per procedure above, but they can be manually overwritten to a different valid account, as needed.
