User Exits & BAPI in MIRO transaction.

Question

Hi all,
We have a scenario as below.
We are raising PO (Say PO No.1) with upper delivery tolerance as 10% at item level. The quantity upto 10% tolerance level is received via movement type 101.
The quantity received above 10% but upto 20% is received via separate movement type say Z01 & PO No. 2 is getting created automatically.
The quantity received above 20% is received via separate movement type say Z02 & PO No. 3 is getting created automatically.
Now consider that Rs. 500 received through 101 movement. Rs. 200 received through Z01 movement & Rs. 100 received through Z02 movement.
Now our requirement is as below.
1. At the time of MIRO,  user will give  PO No. 1 as input. System should through throw message to select PO No. 2 & PO No. 3 also.
2. Following entries should get passed.
101 movement :   Vendor A/C Cr.   500
                             GR/IR A/C    Dr.           500
Z01 movement     Vendor A/C Cr.  200
                             GR/IR A/C    Dr.           200
Z02 movement     Provisional GL A/C Cr.  100
                             GR/IR A/C               Dr.            100
As regards the Z02 movement, we are passing it via GL account tab in MIRO transaction.
After the above entries are passed, system should also raise a debit note for 50% amount of Z01 movement as below.
Provisional GL A/C  Cr.  100
Vendor A/C              Dr.          100
Can any one suggest suitable user exits/BADI/BAPI to satisfy above requirement.

Hi
1. In my opinion, there is no mechanism by which you can tag PO 1/2/3... So, while entering PO1 in MIRO, I dont think there is any mechanism by which you can get a message for Po 2 and 3
You can still try your hand at BAPI_ACC_INVOICE_RECEIPT_POST.... Or go to T code BAPI and explore the right BAPI
2. Regarding other requirements of Z02 and Z01, you can create a Z t code using a BDC for F-02 or BAPI_ACC_DOCUMENT_POST
