Reg:Account Assignment

Question

Hi
I have created PO doc type as ZCAP (for Capital items).whenever we select this doc type we have to select account assignment "A" in Acc.*** Category field in PO line item.As it is manual entry, user (by mistake) is giving "K" instead of "A".
My question how can i make "A" as default to doc type ZCAP.so that whenever we select ZCAP, automatically acc.assign "A" should come and all other account  assignment categories should be deleted.
plz suggest me some way.
Thanks in advance.
Regards,

Hello
There is no standard configuration to control the account assignment with Purchase order document type. Purchase order document type is an header level control where as the account assignment is Item level comtrol.
You need to use Badi to control the account assignemnt category at PO line item level with reference to the PO document type.
Please consider the Badi ME_PROCESS_PO_CUST
Application components: MM-PUR-PO, MM-PUR-PO-GUI : Main program: SAPLMEPO
The Business Add-In (BAdI) ME_PROCESS_PO_CUST enables you to extend the business logic of the Enjoy purchase order on an individual basis. You can thus influence the dialog transactions ME21N, ME22N, ME23N, and ME29N, and the BAPIs BAPI_PO_CREATE1 and BAPI_PO_CHANGE.
Typical applications for this BAdI include:
Processing of own objects
Processing of additional data on standard objects
Implementation of additional checks and derivations
Change of data in standard fields
1. Start of transaction
Documentation for BADI method INITIALIZE
2. Opening of a PO
Documentation for BAdI method OPEN
3. Checking of data
Header data of PO
Documentation for BAdI method PROCESS_HEADER
Item data of PO
Documentation for BAdI method PROCESS_ITEM
Delivery schedule lines of PO
Documentation for BAdI method PROCESS_SCHEDULE
