close PR with customized program in 4.6c

Hello Expert:

i wrote a program to close PR user wanna close.

i used the BAPI_REQUISITION_RESET_REL_GEN to reset the PR, then set the

<fs_eban>-ebakz = 'X'.

<fs_eban>-LOEKZ = 'X'.

when i run the t-code s_alr_87013000 , the amount is not changed, and the PR are still involved in the report result. how can i close the PR completely not to use ME52N, because

MM >Purch. >Req >Rel.Proc. >with class. -->Set up procedure with classification

Push "Release indicator"

Select the release indicator that blocks your PO (e.g. X blocked)

Using the SAP Standard only you have the following two choices that makes the most sense:

- Changebility = 1 i.e. cannot be changed

- Changebility = 4 and Value change = 0,00 i.e. changeable and new release on value change

i selected first one because end-user changed the PR item, the workflow can not be triggered again.

So i have to select 1st option,

Please give me a solution

Kevin
