No commitment document after creation of stock transfer order

Dear colleagues,

I faced with an issue regarding integration between MM and FM.

I am working in ECC 6.0 EhP6.

When I create stock transfer order commitment document is not created. I found note Note 604033 - RKO: Commitments for stock transfer. Which say that I should use create implementation for definition ME_COMMITMENT_STO_CH. This definition has sample code so I added this code to method IS_ACTIVE:

method IF_EX_ME_COMMITMENT_STO_CH~IS_ACTIVE.

DATA: ef_commit_for_sto_is_active TYPE mmpur_bool.

* an initial result will be read as a 'NO' (that means commitments
* for stock transfer orders are inactive)
CLEAR: ef_commit_for_sto_is_active.
result = ef_commit_for_sto_is_active.

endmethod.

After this I changed pricing procedure and unmark condition P101 as statistical.

But after all this settings there is still no commitment documents when I create STO. Could you please advice what else I need to do.

Thanks,

Harry
